hex mesh?
Hello,
I was wondering how it would be possible to create a hex mesh (or maybe use as little tetra elements as possible) for the volume attached, using as reference (fix) the existing 2D surface mesh. Note: file attached is HM 13.0
Thank you in advance for your assistance.

Thank you very much for your reply. I am affraid pyramid elements are out of the question in my case because we use MSC NASTRAN as solver and as far as I remember pyramid elements are not supported.

Yes, MSC Nastran does not support Pyramid elements. However, SAMCEF & NX Nastran work no problem with Pyramid.
Optistruct runs fine with pyramid element.Tried for static analysis.
By using your fix 2D mesh, I don't know how to create Hex mesh, but Tet mesh is possible by accepting some Pyramid elements.
If you want to make mapping mesh, you begin only with one source (section) mesh, not side mesh. Because of important geometrical difference between source and dest section, you will have some 'bad' elements at destination mesh (see screenshots).
