I have to create two kinds of meshes in my model. The first one is hex, the second is tet, and pyramid meshes for the transition bewteen two. we can use the "merge meshes method" tool to complete. Th best way is that we make sure the surface meshes of interface between two regions in distribution and scale are the same.

Just take one simple model as an example shown in fig.0 and fig.00. Hex meshes will be created in the inner region, tet meshes will be created in the out region. I finished the hex meshes in the inner region. In order to better control meshes, surface meshes of out region are created firstly, and want to use T-GRID method (i do not know much about the volume meshes method, i puzzle why ICEMCFD can not create mixed meshes using tri and quad surface meshes directly instead of using "mesh merges

specifically, after finishing the inner hex meshes, i want to create surface 1(in fig.2) meshes based on the mesh points of surface 2(quad meshes).But unfortunately, it does not work, seen in fig.3,4 and 5. It is no use even respect line elements selected. why? how to solve this problem in ICEMCFD? everyone whoever can help me is grateful greatly.thank you all.
