Long before AirShaper was founded, we trained companies on the use of OpenFOAM to support their CAD and CAE design proces. OpenFOAM is an open source CFD (computational fluid dynamics) environment to model a.o. external aerodynamics. We decided to distribute our old course material to help people build their own custom simulations.
