In collaboration with company CFS Engineering, also located at the Science Park of the EPFL, GESTE Engineering proposes the use of the NSMB (Navier-Stokes Multi Block solver) solver.

The NSMB solver is a parallel flow numerical code solving the compressible 2D and 3D Navier-Stokes equations using multi block structured grids. NSMB was initially developed at the EPFL in 1991. Since 1992, the flow solver is further developed in a joint research project between four universities (EPFL in Lausanne, Switzerland; IMFT in Toulouse, France; KTH in Stockholm, Sweden; SERAM in Paris, France), one research establishment (CERFACS Toulouse, France) and three industrial partners (Aérospatiale-Matra in France, CFS Engineering in Lausanne, Switzerland and SAAB Future Products in Linkoping, Sweden). A collaborator of GESTE Engineering has taken part to the software development.

NSMB enables to solve for complex geometries (trains in tunnel, airplanes, space shuttles, turbines, ...) compressible, subsonic, supersonic or hypersonic flows, in steady or unsteady regime. It benefits from several turbulence models (RANS approach) and models for large-eddy simulation (LES approach). NSMB also allows the simulation of combustion problem.
