FLUSEPA code is designed to handle unsteady problems with bodies in relative motion (stage separation) and strong shocks. A finite volume formulation is used to solve the RANS equations. Time integration consists on an explicit temporal adaptive solver. We present a task based parallel version of the aerodynamic solver designed from the previous MPI/OpenMP one and using a modern runtime system to schedule the tasks. An Ariane 5 booster separation computation will be presented.
