Function/Subroutine Documentation

set_mpi_face()

subroutine mod_prepare_mpi_exchange::set_mpi_face

There are 2 sets of variables for faces, either the node located on the face shared by 2 processors are exchanged or not:

• mpi_face_u, mpi_face_v, mpi_face_w: theses faces are not used
• and mpi_face_u2, mpi_face_v2, mpi_face_w2 if they are. This is necessary for MUMPS solver (whereas the above data are used with HYPRE solvers), integration over staggered grid, etc.
