 * Dune-Fem. For more information, have a look at the [official documentation of Dune-Fem](https://www.dune-project.org/sphinx/dune-fem/). The `run.sh` script installs the solver from [PyPI](https://pypi.org/project/dune-fem/) into a Python virtual environment. Please note that Dune-Fem uses just-in-time compilation: The first time you run the solver script, it will take some time.

 It is also possible to use CalculiX as solid solver. In that case, two coupling meshes are needed: CalculiX read/writes temperatures on nodes, but read/writes heat-fluxes on face centers. This requires some adaptation of the `precice-config.xml` file, and [a separate tutorial](tutorials-flow-over-heated-plate-two-meshes.html) has been designed for it.
