+# Wave propagration through fluid-solid interface
+
+This example creates the fluid-solid example with flat ocean bottom from [Komatitsch et. al.](https://doi.org/10.1190/1.1444758).
+
+## Generating the mesh
+
+To generate the mesh for the homogeneous media we need a parameter file, `Par_File`, a topography file, `topography_file.dat`, and the mesher executible, `xmeshfem2D`, which should have been compiled during the installation process.

+>!  Currently, we still use a mesher that was developed for the original [SPECFEM2D](https://specfem2d.readthedocs.io/en/latest/03_mesh_generation/) code. More details on the meshing process can be found [here](https://specfem2d.readthedocs.io/en/latest/03_mesh_generation/).
+
+## Running the mesher
+
+To execute the mesher run
+
+```
+    ./xmeshfem2D -p <PATH TO PAR_FILE>
+```
+
+>! Make sure either your are in the build directory of SPECFEM2D kokkos or the build directory is added to your ``PATH``.
+
+Note the path of the database file and :ref:`stations_file` generated after successfully running the mesher.

+## Running the solver
+
+Finally, to run the SPECFEM2D kokkos solver
+
+```
+    ./specfem2d -p <PATH TO specfem_config.yaml>

 # Wave propagation through homogeneous medium with no interfaces
+
+In this example we simulate wave propagation through a 2-dimensional homogeneous medium.
