Altair CFD’s smooth particle hydrodynamics (SPH) solver is ideal for studying high-deformation free surface flows. Whether it is a vehicle passing through a body of water (pool or a puddle) or water sliding down the windshield and into the engine bay – you will get extremely fast results. It is possible to perform an analysis of various vehicle under-body designs under different water wading scenarios and choose the optimal design based on structural integrity of the body panels and desired water reach.
