Improving orthogonality for OpenFoam
 

Hallo,

I have to create a tetra mesh for the interal space of a car in ICEM CFD for OpenFoam. When puting the prism layer in to the mesh the orthogonality decreases. This is badly for the numeric of OpenFoam. Are there some rules to follow for avoiding this drawback.

Thanks.

I could localize (red encircled region) the elements for my problem. Because I'am new in tetra-meshing I have no idea to fix those regions. I try to understand the different setup with the guideline and try it, but without success. Has someone an idea?
