Add Parasolid model support

[usmanriaz07]

This PR:

• adds Parasolid geometric model support to M3DC1.
  • this is done by enabling PUMI model .dmg support in M3DC1.
  • see section 3.5 in the M3DC1 document to convert Parasolid geometry into PUMI model .dmg and mesh .smb.
  • to load the updated model, just define the name of model file using the parameter mesh_model which is the same parameter that is used for regular .txt model.
  • an additional file containing some of the model information is defined using model_info. This will be generated by the routine that prepares PUMI model and mesh from Simmetrix model and mesh.
  • Example:

    mesh_filename = 'STAR.smb'
    mesh_model = 'STAR.dmg'
    model_info = 'STAR_modelInfo.txt'  
  

• To compile M3DC1, update SCOREC_DIR in stellar.mk (only available on Stellar for testing). Replace the following block:

ifdef SCORECVER
  SCOREC_DIR=$(SCOREC_BASE_DIR)/$(SCORECVER)
else
  SCOREC_DIR=$(SCOREC_BASE_DIR)
endif

with

/projects/M3DC1/SCOREC/install/m3dc1_scorec/2026-05-22

Try to look for the latest version of m3dc1_scorec in /projects/M3DC1/SCOREC/install/m3dc1_scorec/ and use it. They are organized in terms of dates.

To make sure the code is not breaking for older m3dc1_scorec installs, a flag CAD is added. If CAD=1 at compilation time, the m3dc1 install needs the latest version of the m3dc1_scorec. Otherwise, any version of m3dc1_scorec is compatible. For example, to compile m3dc1_2d with this option:

make OPT=1 RL=1 CAD=1 MAX_PTS=25 ARCH=stellar

Example STAR Test case (just model and mesh files) is provided in:
/projects/M3DC1/SCOREC/examples/2026_02_18_UpdatedModel_STAR

@usmanriaz07 is this PR ready to merge? If so you should remove the draft status. If it is not ready, please clarify what work is remaining.

[usmanriaz07]

@nferraro @jchensw I have added a flag CAD for compiling latest changes in code. If its not used, m3dc1 should compile with older versions of m3dc1_scorec. Can you please have a look at the changes, and if they look good we can merge the changes to master.

[jchensw]

I just tested on Perlmutter GPU nodes. All regtests passed except adapt.
The adapt case failed with a segmentation fault, while the adapt built from master branch works fine.

[usmanriaz07]

Thanks Jin. I have never installed m3dc1_scorec on Perlmutter before, if you can share the instructions with me I can debug the issue myself. Or if possible can you please provide me more details of the failed test? Execution report before segmentation fault might help.

[jchensw]

Sure. First set up environment using

cd Your-M3DC1-HOME
export M3DC1_CODE_DIR=pwd
module use $M3DC1_CODE_DIR/unstructured/modules/perlmutter
module load m3dc1/devel-gpu-gcc

Then go to "m3dc1_scorec" directory, and configure it with

PETSC_DIR=/global/cfs/cdirs/mp288/jinchen/PETSC/production/petsc.20230606
PETSC_ARCH=perlmuttergpu-gnu-860
PARMETIS_DIR=$PETSC_DIR/$PETSC_ARCH
ZOLTAN_DIR=$PETSC_DIR/$PETSC_ARCH
SCOREC_DIR=/global/cfs/cdirs/mp288/jinchen/PETSC/production/core-240527/upgrade-gnu860-pgpu
PREFIX=$SCOREC_DIR

cmake ..

followed by "make install". then go to "unstructured" dir, build m3dc1 with "make all ARCH=perlmutter_gpu_gcc".

@jchensw Thanks for the instruction. I don't have access to some of the directories so couldn't install m3dc1_scorec. I tried accessing the following directory but had no permission:
/global/cfs/cdirs/mp288/jinchen/PETSC/production/core-240527/upgrade-gnu860-pgpu/

I am not a part of group mp288, so my guess is I will need to be a part of this group to get access.

[jchensw]

permission is granted. pease try agian.

[usmanriaz07]

Thanks Jin. I just compiled m3dc1_scorec and m3dc1 targets. And now running test cases. I will update here once I find out what's going wrong with the adapt test case.
