1. How to install?

Warning: Check carefully the MPI version you want to use for parallel computing before installing the code, especially onto a HPC cluster.
The command mpicxx should be found into the bin directory of the MPI version you plan to use, to check that, run:
type mpicxx

2. How to run preinstalled version?

30/03/21 (TRUST) Bug fixed : Useless write of a result file (containing mesh only) with no fields post_processing block
30/03/21 (TRUST) Bug fixed : Add messages to enhance PolyMAC use : detect incorrect mesh or time scheme
30/03/21 (TRUST) New option : Add convertAllToPoly option to LireMED keyword to convert mixed type cells mesh (eg. tetra and hexa) to polyedras/polygons only cells
