VECTIS

What is VECTIS?

VECTIS is a three-dimensional fluid dynamics program that has been developed specifically to address fluid flow simulations in the vehicle and engine industries. VECTIS is developed around a completely automatic mesh generator, providing a rapid turnaround time for CFD analyses. The fully automatic mesh generator, unique to VECTIS, provides a distinct advantage over most other commercial CFD tools; in that it ensures CFD is an integral part of modern engineering development programs.
