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).<\/p>\n<p>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.<\/p>\n<p>Any tips or advice here would be greatly appreciated.
