Development of a simulation code for rarefied gas flows

Participants : Luc Mieussens [Corresponding member] , Florent Pruvost [IMB, engineer] .

The simulation code CORBIS (rarefied gases in 2 space dimensions on structured meshes) has been entirely modified: modular form, use of the git version control system, modification to use unstructured meshes, MPI/OpenMP hybrid parallelization. Very good performance in terms of scalability and efficiency have been obtained, up to 700 cores.
