News

The v26.06 release is out! Thank's to all the contibutors - developers and users - who made this release an even better version of SOFA
Training session planned on July 31st: available free seats

Technical discussions

#6172 [Core] Start discussion about higher-order topologies
Alex worked on dynamic topologies to assess the implementation of a generic function
#6176 [Plugin] SofaCHOLMOD: Add plugin with a supernodal Cholesky direct solver (EigenCholmodSupernodalLLT)
Performances are strongly impacted by the version of BLAS used (Linux) which is only checked at runtime. Not optimal. MacOS accelerate is using the optimized version of BLAS. Not yet tested on Windows. To be tested by core-devs. Cholmod doesn't need a reordering method but the current API forces to provide one that'll be ignored (because an internal one is already used).

Technical discussions

#6172 [Core] Start discussion about higher-order topologies
- This PR is a suggestion to support higher-order topologies. E.g. access topology of quadratic tetrahedron from a BaseMeshTopology. BaseMeshTopology is an abstract class and most functions are hardcoded (plus functions to access neighboring information). To do so, the PR proposes an new homogeneized API which can be extended with new element types.
- One weak point raised was that we need to explicitly add all types with their corresponding enum, duplicating static knowledge. But it is not easy to do it dynamically, especially for component interfaces.
- Compatibility with existing data structure is proposed
- Implementation should be rigorous on the const aspects.
- Missing features (neighboring elements) might not be needed for rendering and physics computation. So next steps would be to test these directly in rendering and FF. But before going to FF, engine to produce those higher order elements will be needed.
- For masses, the surrounding elements will be needed. Of course, starting simple with physics is good, but we need to keep an eye on all corner cases (all dynamical topologies will be tricky because of hardcoded topological changes methods)
- Another issue to think about in the future are mapping which are currently though of for linear elements (especially barycentric mappings).
Contribution of CholMod linear solver might take place soon (by Fred)
Coupling with PETSc : could be done through the Python bindings of linear solvers

#6169 [Mass] NodalMassDensity: add explicit registrations to float and double instead of SReal
This and the following two PR are related to the SOFACuda Work on adding GPU version of the new FEM. Some template types where missing (here float, for the next, the element type and so on...) → ready
#6168 [All] Introduce Snapshot feature
SnapshotJSONExporter and SnapshotManager are introduced. Review is needed. Some changes to come soon since the feature is very GUI-dependent.
Sanitizing the scene names (without spaces) should be done separately (regarding the associated regression regeneration) → keep to review
#6164 [Helper] Messaging: add msg*once macros to display a message only once per component instance
Add one example of use in the codebase → keep to review (then ready)
#6145 [Framework] Cmake: set warnings-as-errors in all the Framework targets
Need to wait for the CI migration. Plus the Windows compilation is already failing, we will need to fix it → keep to review

Lucas did not have time to work on it. This PR is linked to the snapshot feature #6168 and should be close to an end → wip
#6117 [All] Introduce integration schemes
A sprint will be done by Paul but some work is needed to regenerated unit tests → wip
#6073 [Diffusion] Explicit MechanicalObject link
It seems that Gaetan faced an issue to use a PCG preconditioner using a CG linear solver, then asked an AI to solve the issue. The original PR is about adding a link. However, all ForceFields are SingleStateAccessor, which are member called mstate and already are a link to the mechanical state → keep to review

SOFAPYTHON3 PR review

#625 Introduce rigidification example/tutorial

STC#21 took place last week in Strasbourg, the associated report will be soon released online.

Technical discussions

The release process for the 26.06 has started. The branch has been frozen on every plugin and in the main repository. The release will be generated once the binaries meet the requirements.
#6167 [CI] Update pixi lockfile
Failing for windows and ubuntu. We want it for the release
#6161 [Core] Improve UX when defining template of a Component
Superseed by 6162 that is more complex
#6162 [Core] Rework the component factory
Rewrote the factory from scratch to review the process of creating a component.
- Breaking
- Cleaned the data structure defining the component (ClassEntry), replaced by a list.
- It also changes the way components are registered in the factory. The idea is, instead of having one registration per object per template, the registration is unique with multiple templates. A work has been done to make those entry independents in the factory
- Now the module has to be defined explicitly
- Name of the component no longer rely on the reflexion mechanism in SOFA
- Remove the use of static class function used in the factory (getCustomClassName, create, canCreate). Create could be completely deleted from the API.
- One effect is that we can create a component even if it doesn't match the current context (like when creating a mapping without mechanical object)
- Template deduction rule is not implemented in the factory any more, and because the create method doesn't exist anymore, we need to specify it when we register the component
- Template attribute is not "template" anymore but is set by the registering method.
- Same for the element type
Comments on reflexion mechanism
- Reflexion is a complexe mechanism to keep but it is usefull anyway to avoid having names completely unrelated to the C++ symbol name.
- Anyway the current implementation will keep it for compatibility issue, we can later think of what we want to do with it
Comment on template name
- Issue with the fact that now we will have multiple names for the same exact mechanism. It will be difficult to follow for the users.
- This mechanism adds a new attribute that can be modified by the dev and the issue is that if we force the dev to name it, we will end up with many different template name attribute.
- The idea of having a default name so that there is no need to redefine it each time might solve it.
- Some idea was proposed on putting the template name in the component but that would be difficult because it removes the template deduction mechanism.
- We need a 1h discussion with interested devs (especially Damien)

SOFA PR review

#6167 [CI] Update pixi lockfile → see technical discussion
#6164 [Helper] Messaging: add msg*once macros to display a message only once per component instance
This PR is to ensure that a message is only sent once (not repeated multiple times). It is using a local structure that register when it has been called. The mechanism is a bit complex but does the job properly. Let's keep it open for next week.

Technical discussions

Skills for compatibility layer by Paul: https://github.com/bakpaul/AI-skills/tree/main/custom-skills/sofa-compat-layer
- existing one on CMake, now we have another skill
- not restricted to Claude
- next : Lifecycle, integration of SofaPython3, possibly merging the design pattern PR suite
Plugin SOFA.FloatPrecision made by Alex to change the floating point precision : if you want to compile it with double precision, and with float, the script creates another dynamic library
- This investigation led to some fixes (see PR)
- Mixing precision is common to gain in performance. Instantiation of SparseLDLSolver in float which seems to slow down the simulation (possibly due to many conversions)
- Another solution would be to add some factors in the linear system so that we have a 'unit' linear system
Write new material laws in Python is becoming easier and easier. An example here is available with St Venant Kirchhoff
- This is a part of the roadmap : providing bindings for hyperelastic materials
- Hyperelasticity seems to work as expected
- Only 3 functions to overwrite
- Next : second type of material using the SPK (Second Piola Kirchhoff). However, this will have downside : huge overhead using python conversion
- A next step woul dbe to use autodiff to help building such FF.

#6159 [examples] Use CCD for example scene Update comments. And update regression test → Then ready
#6154 [SolidMechanics][FEM] Fix FastTetrahedralCorotationalForceField stiffness matrix assembly Issue when loading mesh from GMesh. If you forward it to the topology container using src, or using link the result is not the same, and worse it is wrong. This is because sourcing will copy the edges but those edges are not computed the same way by the loader and the topology. Wait for the CI with all tests. → then ready
#6153 [Spring] Enable dynamic update of spring stiffness Dynamically changing the stifness of springs was not possible until this PR. It is needed for SOFA.Diff → ready
#6152 [Core] DrawMesh<Hexahedron>: add quick test for quads when drawing hexa This doesn't solve everything, it prevents crash but some topology will still not be drawn. We might fix the topology to compute those sub elements each time. → ready

#621 add binding to convert elastic parameters to Lamé's parameters It would be nice to see an example of this binding. → keep to review
#620 Fix/add/test Mat bindings Related to the technical discussions. Some of the bindings were broken and no test was implemented. This PR fixes the one already implemented and add tests. But anyway, converting to numpy whould be the way to go when using matrix in python. Python "self" should return itsef for the binding to be supported by PyBind11 → ready
#619 export symbols for BindingBase to be used in other libs → ready
#618 Replace deprecated PYBIND11_OVERLOAD* by PYBIND11_OVERRIDE* Update the minimal required 2.6 version for PyBind11 → keep to review
#617 [Python] Set the current cwd to the scene's path We should avoid changing the current working directory. The path of the scene file should be added to the list of path. This PR is too breaking and we should merge the PR in SOFA → close

#6135 [Helper] FileRepository::findFile(): use the list of paths when given a dotted path This PR is changing the behavior of file search in case of relative paths (relative to the list of paths). But it might bring perturbations with other libs. runSofa (+SofaPython3) and Python do not use the same, respectively the script path and the path from which you run Python. Sofa.Runtime could set the current working directory, consistently with runSofa. To be rediscussed → keep to review
#6125 [Simulation.Core] WorkerThread: fix memory leak/resource retention Test has been added and fixed → ready
#6124 [FEM] Refactor templates in latest FEM classes This PR should be discussed (it's for now more a PoC). Important we should avoid repeating things. Possibly deducing DoFs template, deducing elements might be more complicated when having mixed elements. Note that it also requires users to know the existing templates.

#6141 [GUI] Factorize camera related code to use in child class → ready
#6139 [FEM.Elastic] introduce virtual method called before force derivatives Not used directly in the COre but needed for the hyperelastic forcefields. It mimics design already present in classical forcefield in addForce. → ready
#6133 [FEM.Elastic] Remove complex unproductive stiffness matrix data structure Remove the local factorized version of stiffness matrix because it seems to be slowing down results. This is certainly due to the use of the Voigt mapping that is difficult to be optimized by the compiler. The benchmarks show real speedup. We can see the speedupt everywhere except for tetra on ubuntu. Anyway, this is not a "dealbreaker" because it still simplify the API for not too much loose. → ready

#6125 [Simulation.Core] WorkerThread: fix memory leak/resource retention It only adds a test to show the error, the fix will come soon. → WIP
#6124 [FEM] Refactor templates in latest FEM classes We would also like to remove the prefix 'Element' from forcefields names. But the issue is that this name already exists as a "prefab" instanciating the proper template given the topology. In the real prefabs we expect the user to specify the element type once. So it would be great to also have a way to only specify once the element type, as a template for every type or as a component in the scene 'Tetrahedron'. For this PR we will start by removing the templated classes and add it to the template. → keep to review

Scientific & Technical Committees with members take place this week
A SOFA paper could be a good idea to:
- provide a up-to-date pitch for SOFA
- highlight the current features
- share our vision of the project

Technical Discussions

Fork the CollisionAlgorithm plugin (GPL) at InfinyTech3D, including history and reference to the original project
Regression in Python is fully home-made
#6103 [plugins] Change Cosserat plugin GIT_REF from master to main
- The actual maintained branch is the main branch
- We would like to build it in the CI at one point
- We will test it in the CI by creating a PR adding it to the supported plugins
SofaImplicitField, SofaDistanceGrid, Cosserat officially supported ?
- It has been accepted to put the two first as supported as they are already tested and built. We could also take them out of the main repository.
- Cosserat will wait for the CI to say it is good
Documentation of the plugin SofaPyhon3
- OK to simplify the documentation
- Having a readthedoc is fine for self-contained Python project, SofaPython3 should be merged within SOFA and its documentation too
- a first step could be to merged the plugin within the SOFA repository as the Sofa.GL repositories
Float compilation
- We want to keep it but we need to test it on the CI somehow

Short question from Leo : how to build an augmented system for constraints so that they can be solved directly
- Alex started to work on this, it is paused for now (still on the roadmap)
- Possibly using InteractionForceField
Presentation by Lucas Burel : save and load snapshots of a simulation
- Struggling with using Links extraction
- Graph structure not saved: need to load the scene

First demos by Tristan Cordeboeuf for VFX with SOFA

Technical Discussions

Alex presents his work on symbolic automatic differentiation plugin for SOFA
- new tool to implement new FEM models
- based on nothing, on a symbolic library SOFA.Symbolic made with AI that has only one dependency which is SOFA
- only needs the implementation the energy computation in one element (in the energyFunction function)
- At init the forcefield will generate/compile the derived functions (gradient for the force and hessian for the stiffness matrix)
- Using hash of the symbolic expression, it is able to cache the compiled functions to avoid rebuilding at each launch
- Can be used to derive the forces with respect to the parameters for differentiable simulation using the SOFA.Diff plugin
- Wish-list
  - Python bindings could be added in order to create new forcefield in Python using energy expression
  - It could be thought how to make so that user could still change the mechanical parameters of the material law while the simulation is running
  - It would be nice to abstract this for all types of elements
Leo will present in an upcoming SOFA dev meeting his Sofa.Diff plugin. Release and presentation coming soon. Stay tuned!
Paul is working on a big refactoring of ODESolvers and AnimationLoop to enable the use of NewtonSolver with Lagrangian constraints that'll break a bit the API. He will make a presentation of the design in upcoming meeting.
Documentation process should be updated
- the master branch as a working version
- the website should display only the latest release (currently v25.12)
Duplication of FEM based forcefield/mass (with Alex's recent contributions)
- Promotion and presentation at the next release (v26.06)
- Switch all scenes using the new components
- Start the deprecation (v26.12) to plan a deletion (v27.12 or later)
- We don't ant to delete the old one directly, to make sure demos are stable and behaves the same before.
- Still not compatible with topological changes
- Engine could also be implemented to allow user to input the total mass (instead of mass density)

#6063 [CI] Update pixi lockfile
- PR is not triggering the Pixi CI, except when a pixi file is modified
- PR is green on CI 👍
- Remark: hard to trust updates of so many packages
#6044 Eigen 3.4.1 and 5.01 available and more third party updates
- SOFA supports the last Ubuntu LTS which means that the version of the dependencies is frozen for two years each time, while allowing ourselves to update some sparsely. All dependencies will be updated at once for the next LTS
Question : how to generate a mesh with quadratic elements?
- MechanicalObject needs to be extended, the elements too
- Discussions with Mimesis could be of interest
- VTK seems to support quadratic elements (cell type name, vtkQuadraticTetra)
- Missing : mappings for quadratic, even if we could use our existing linear mapping
Cuda code : we might try to implement new version of linear solvers on GPU starting from the example of the CudaSparseLDLSolver of Alex, and maybe a CG using AI agents. Might also rework the CPU version of the LDL using a new lib doing sparse work SuiteSparse.

#6025 [SceneChecking] Introduce SceneCheckSpecialCharacters Special characters in object names break links paths. This scene checker ensure that those characters are tracked and warning displayed. PR [#6026 [Simulation.Core] Refactor logic of loading a plugin from a RequiredPlugin name] tries to automatise the required plugins case where the name is used intead of another data. But we really should disable this feature. A compatibility layer will be added by Alex.
#6031 [Tracy] Fix compilation when enabling Tracy A PR broke the compilation of SOFA with Tracy because it uses a dynamic name when Tracy expects constexpr. To fix this a new PR introduced a new set of macro enabling this. It works with Tracy now, but the issue is that still, the CI will not see when it is not used for future dev. #6036 introduced a compile time check so that in the future we will track those errors.
Question about dropping explicit solvers. They are a good entry point for ODE solvers in term of learning and also for testing dev. It might even be relevant for multiphysics simulations.

#5916 CMake & Nix: add tight_inclusion
- process to add a rockies dependency (Tight Inclusion)
- should be validated by STC
- researchers coding, not finished
- present in conda but cannot install properly : patch not in upstream (divergence between packages)
- symptomatic error : know what you miss
- define our relationship with the authors
An evolution of the process of adding a dependency in the core is needed. To make sure every time a dependency is added we need to make sure every consequences are though of.
target SofaGTestMain
- target to be linked against all targets for unit tests
- allow to init() and cleanup() before and after all tests
- install is not done usually since we do not distribute it
libraries targets sorted in a folder ⁨libraries⁩despite the commandset_target_properties(${PROJECT_NAME} PROPERTIES FOLDER Sofa.Framework)
- command Sofa.Framework is useless : two contradictory intentions sofa_add_* (module/library/plugin) will do the sort, Sofa.Component will overwrite to sort into a Sofa.Component folder
- clarify this later
#5891 [Core] BaseObject: remove components from the slave list
- if a component is overriding this function and not calling super::cleanup()
- the template method pattern would solve this
#573 [Controller] POC: overall speedup

- Need to take a dynamic change of the method into account (see pr comment)
#5938 [Type] Default constructor zero-initialized
- we had a component if not initialized (with no_init). This has been changed since #4396
- this went un-noticed due to the compilers we use

News

Exceptionally the SOFA dev meeting took place on Friday afternoon
v25.12 release should come before the end of January !

Technical discussions

Issue with Metis (see ##5878), the binaries are crashing in the Eigen support code for Metis when version is 5.2.1. Full debut mode is not helping analyzing the bug. The error stops when simulation speed decreases, thus possibly linked to multithreading. For the release, we suggest to roll-back to 5.1.0. Either the problem is in SOFA else we should signal the issue to mark the Conda package as broken. EigenSimplicialLDLT using Metis is crashing too. This would advocate that since SOFA + Eigen experience the issue, the problem origins in Metis.
Blinking LCPForceFeedback_test #4671: rather than deactivating the test, we could investigate the number of iterations computed by the Gauss-Seidel in the LCPForceFeedback and decrease this number (+ update the reference values)
#5882 [FEM.Elastic] Introduce generic element-agnostic elastic FEM force field: this comes from the Elasticity plugin. Linear elasticity is introduced in two different classes : pure linear elasticity and co-rotational elasticity. PR is not finished yet. The component agnostic from the type of element is not yet added. Other features like test codes, benchmarks (in C++, in Python), the mass (not necessarily restricting to a tensor mass implementation, approximating non-simplex cases), plasticity are still present in the plugin.

Technical discussions

#5878 [tools] Remove autoload of Sofa.Metis for windows
- Couple of scenes are crashing due to metis, only occurring on Windows. It might take time to fix it, that's the reason why the suggestion is to remove it from autoload
- The bug does not occur with Pixi
- Ideas to investigate
  - Test binaries from Pixi and investigate the Pixi patch
  - Try the release without CGAL to see if it solves the issue
- OrderingMethod for a direct solver is a property hidden to user, which is based on a plugin (Metis) by default if one is found. We could find an alternative Scotch
#5869 [CMake] Remove CGALPlugin from supported plugins
- Half of Ubuntu compilations fails due to CGAL plugin memory issues
- Only MeshGenerationFromImage is a valuable code from the plugin, the rest has equivalent in Python
#5875 [Lagrangian.Solver] UnbuiltConstraintSolver: implement hotstart
- Hotstart for unbuilt constraint solver
- Performance drop when using UnbuildConstraintSolver instead of LCPConstraintSolver
- Let's make a deeper review on this pr now we know that it has been generated by AI
- Part of this work was partially generated from an AI, how to manage such AI-generated codes: define a flag "pr: ai-generated" to notify reviewers
- Jacobi could also undergo the same changes (see with Paul)
#94 Running SofaRegressionProgram on SOFA /examples directory
- 20 out of 67 regressions are actually tested (30 are not tested, and warning silently)
- Name of the MechanicalObject is used to generate the state export. However. The default name was "MObject" and it has been updated to "MechanicalObject", the CompareState did not find the reference (without throwing a warning/error as stated in #45)
- We also need tom implement other metrics in the next python script for regression because the current way of doing it accumulated errors during the simulation. So very clone behavior might break the regression.

#92 [scripts] Update SofaRegressionProgram to export in CSV format The version of the RegressionProgram could be added, regarding backward compatibility. Why not keeping both (csv and json) but then we might face issues of coherency, compatibility. Lucas is working on comparing serialized exports from SOFA. This could be extended to the regression. → keep to review

Awards : discuss format
- either two prizes for the two-best contributions
- or one prize for the best contribution and one for the best SW26 presentation

Discussion concluded on the fact that we would need clear criteria also for the presentation but it is a good idea if it helps us to save time and if it helps people into making a presentation

Technical discussions

Release update
- work on plugins
  - OOT compilation of plugins is tested (most PR are even merged)
  - SofaPython3 fails on MacOS for stub-generation
  - SoftRobots.Inverse fails for Conda CI : nightly due to tight-inclusion
- ffmeg dependency must be distributed for Windows and fixed on other os
Update on the project Template Method design pattern
- many PRs opened
- test of all PRs will be merged for test in one branch
- remaining task : BaseObject
Parallelism in Elasticity plugin
- The code uses a std::for_each using a ExecutionPolicy
- Provides a generic implementation for both parallel and sequential policies
- std policies are really faster than our task scheduler
- compiler support is still an issue : MacOS does not support the feature at all so far (installing tbb and possibly forcing the sequential execution on MacOS could be done)
- comparison with TaskFlow would help to benchmark to evaluate if it makes sense to replace the TaskScheduler with TaskFlow
Viser visualization: viser.studio
OSQP has been reimplemented in ProxSuite
- ProxSuite reimplements it for comparison and benchmark purposes (dense system mostly)
- mim_solvers
#5841 [Collision] Introduce multi-staged collision pipeline
- Presented at the STC
- Allow to have different collision pipelines in a scene
- Issue : all links are explicit, and linking possibly on a not-yet created object
- Should implement an inheritance between multi and CollisionPipeline which is a special case of multi that have only one SubCollisionPipeline
- Might be good to rename Multi into Composite
- Remove the sorting of pipeline regarding the alarm distance
- Problem of thread safetiness on response creation inside of the Barycentric mappers
#5814 [Type] Add optional support for mimalloc
- so far the option is added, but OFF by default
- if distributed through Pixi, the VM (Ubuntu + MacOS) could activate it later
