+# Tutorial for an FSI simulation of an elastic flap perpendicular to a channel flow
+
+This tutorial is described in the [preCICE wiki](https://github.com/precice/precice/wiki/Tutorial-for-FSI-with-deal.II-and-OpenFOAM).
+
+It is known to work with OpenFOAM 4.1, 5.0, v1712, and v1806, but it should also work with newer versions. Have a look into our [Notes on OpenFOAM](https://github.com/precice/openfoam-adapter/wiki/Notes-on-OpenFOAM).
+
+You may run the coupled simulation in serial using the script `Allrun` or (OpenFOAM) in parallel with `Allrun -parallel`. The output of each step will be redirected to log files. You can cleanup the simulation using `Allclean`.
+
+If you prefer to run the two simulations in two different terminals and watch their output on the screen, use the (simpler) scripts `runFluid` (or `runFluid -parallel`).
+
+Before starting the deal.II program, it needs to be compiled and copied in this case directory. Information about building is collected in the [deal.II wiki](https://github.com/precice/dealii-adapter/wiki/Building). You can Use the following command to run e.g. the linear deal.II solver afterwards:
+```
+./runSolid -linear
+```
+
+There is an [open issue](https://github.com/precice/openfoam-adapter/issues/26) that leads to additional "empty" result directories when running with some OpenFOAM versions, leading to inconveniences during post-processing. Please run the script `removeObsoleteSolvers.sh` to delete the additional files.
