Fluid dynamics simulation

We help engineers make better, faster decisions through fluid flow simulation, from the design phase to products in operation.


Powerful and highly accurate CFD solutions for every engineer

Our CFD (Computational Fluid Dynamics) simulation technology is used by some of the largest companies in the world for its superior computing power and accurate results that can optimize and predict the performance of products and systems. At the same time, it is user-friendly and accessible to engineers at all levels, in industries of all shapes and sizes, such as aerospace, automotive, and industrial equipment.
