Drag on a Race Car:
Simerics-MP+ can be effectively used to predict external and internal (e.g. under-hood) aerodynamic drag and has been validated by comparison with classic data such as the Ahmed body. The advantage of using Simerics-MP+ for aerodynamics is the ease and ability of the general mesher to create a mesh, even for a “dirty” geometry, and the speed of the simulation which has been reported to be 10-30 times faster that the competition.
