When we have partitoned a mesh with feelpp_mesh_partitioner, we would naturally like to read the output file in order to extract data and work on. That’s the purpose of mesh.cpp.


From the file given by the option mesh.filename, the programm can extract the data and load the associated mesh into our execution. With this, we can give a json file, obtained from feelpp_mesh_partitioner and it will retrieve the parts of the original mesh.
