summary: We solve a simple heat equation. The domain is partitioned and the coupling is established in a Dirichlet-Neumann fashion.

* OpenFOAM. This case uses the custom [heatTransfer](https://github.com/precice/tutorials/blob/master/partitioned-heat-conduction/solver-openfoam/heatTransfer.C) solver (find it in `solver-openfoam` and build with `wmake`).

The G+Smo-based version of the tutorial offers IsoGeometric Analysis discretization method. To run the example you need to follow the following steps:

- Download G+Smo and Create a Build Folder

### Note on the combination of Nutils & FEniCS

You can mix the Nutils and FEniCS solver, if you like. Note that the error for a pure FEniCS simulation is lower than for a mixed one. We did not yet study the origin of this error, but assume that this is due to the fact that Nutils uses Gauss points as coupling mesh and therefore entails extrapolation in the data mapping at the top and bottom corners.

For Nutils, please use the files `Dirichlet-*.vtk` or `Neumann-*.vtk`. Please note that these files contain the temperature as well as the reference solution.

For G+Smo, please use the generated `solution.pvd` files in the dirichlet-gismo and neumann-gismo directories.
