Simulation of pitch blade impeller with 10M particles injected at t=0


M-Star CFD is a software tool that simulates real world systems with unprecedented accuracy. The high fidelity results are driven by Large Eddy Simulation and advanced lattice-Boltzmann algorithms. These techniques are able to exploit modern computing architectures.

M-Star uses Large Eddy Simulation (LES) to produce incredible results of your real world system. The flow fields realized by this approach offer highly detailed flow structure information. We are then are able to layer on other physics, such as transient chemical reactions and particle motions.

We work closely with each and every client to ensure they drive exceptional value from our product.
