I am looking for some help generating a good mesh and was wondering if anyone has any ideas.
Attached are screenshots of the best hex-dominant mesh i have been able to generate and the associated settings. The problem is the highly skewed elements between the fine inner mesh and the coarse outer mesh. I prefer to avoid tetrahedrons due to the large number of elements generated, however i do get a good mesh with tetrahedrons (based on skewness).
It seems to me, the mesher should generate successively smaller hexahedrons to step down to the smaller elements, but instead it generates apparently random tetrahedrons and such.
Any tips or advice here would be greatly appreciated. Thanks!
