CMPS is a Computational Fluid Dynamics (CFD) simulation software being developed in partnership with ROKETSAN Missile Industries with unique capabilities. CMPS and Hydro are based on the same framework with different solvers. CMPS has a unique ability to solve all equations describing different physical phenomena in a fully/strongly coupled manner. This provides real-time accuracy for complex dynamic simulations. This also provides robustness and fast convergence rates for steady-state calculations due to the fully implicit coupled solution of coupled physics flow.
