great example, many thanks!

two suggestions for future use:

1. let us choose a different name, to make the name a bit more explanatory about the example setup.
   
   -> i can do that as i'm going to create some new subfolder structure in the EXAMPLES/ similar to the 3D_Cartesian version, where we have benchmark, applications and reproducible_study subfolders.

2. the Par_file ordering has changed slightly in the meantime, the nbmodels section is now mostly only used for internal meshes, whereas external meshes should use a MESH/nummaterial_velocity_file instead to define the material properities. you will find such an updated usage in the EXAMPLES/Gmsh_example_Stacey_MPI. this is to make the look-and-feel of the examples using external meshes in 2D and 3D_Cartesian versions more similar.
   
   -> i'll do that when updating the EXAMPLES/ folder soon...

Hi @danielpeter,

Thank you very much for merging my PR and explanation on how the material parameters should be set with external mesh currently!
I will modify my example to replace nbmodels to use MESH/nummaterial_velocity_file then reopen a merge request soon.

Thanks!
