Hi All,

I am going to mesh the model with hybrid meshes. Part with tetra, and hexa for the other one, both of them were supposed to include boundary layers. It is easy to get the prism layers with a specified growth ratio for tetra mesh, but not that easy for hexa mesh. In order to keep the consistency of the mesh nodes on the merging interface, to be better recognized when merging, the thickness of the near wall layers of hexa need to approach that of the tetra as much as possible. Splitting edge by specifing the split ratio would work, but need to manually calculate it since only one cut could be done in one operation. More layers needed, more complicated for the boundary layers be generated. As an alternative, I checked on the Use Existing Quad Layers option to generate prsim on quad meshes, but no matter what numbers were given for the layer numbers, ratio and initial height, the first layer always be equally split. Anyone have such a problem? I am thinking that it is a BUG of ICEM.

How did you do to get the boundary layers when obtaining hybrid meshes? Detailed procedure would be very appreciated. Thanks for any information.
