 To run the first scenario execute `mpirun -n $number_processes python3 run_mc_Kratos.py`, while to run with runcompss the second scenario execute `sh run.sh`.
-In the latter case, the environment variable `EXAQUTE_BACKEND` has to be set to `pycompss`. In the former case, the environment variable `EXAQUTE_BACKEND` has to be set to `local`.

 We remark that the mesh discretization we upload in this repository is rather coarse, since only 300000 elements are used to discretize the domain. The discretization can be observed next. The whole domain is reported in the left figure and a zoom close to the building is reported in the right figure.
