OpenFOAM - Overset

Learn how to use effectively overset (chimera) meshing in OpenFOAM in all engineering sectors, especially transportation: Automotive, Aerospace, Marine, Rail.
CFD Engineers with interest in overset (chimera) meshing method.

The course covers theoretical and applied concepts using overset (chimera) meshing in OpenFOAM. The training provides examples of process and best practice, which are useful to existing OpenFOAM users wishing to broaden their application knowledge of OpenFOAM towards using overset meshing as an alternative to mesh morphing or sliding interfaces. All features demonstrated in this course are part of the Official release of OpenFOAM.
