M-Star CFD

M-Star CFD

M-Star CFD is a multi-physics modeling package used to simulate fluid flow, heat transfer, species transport, chemical reactions, particle transport, and rigid-body dynamics. M-Star CFD is developed, maintained, and supported by M-Star Simulations, LLC (“M-Star”), based in Maryland, USA.

M-Star CFD contains three primary components: M-Star Build, M-Star Solve, and M-Star Post. M-Star Build is a graphical interface used to prepare models and specify simulation parameters. M-Star Solve uses input files generated from the interface to execute the simulation. M-Star Post renders and plots data generated by the solver.
