Meshing Two Components with Shared Boundary
Altair EmployeeI've been working on meshing two imported component geometries with a shared boundary for the last month, but have had no success despite browsing the forums and Hypermesh help, so hopefully someone here might have an answer.
Briefly, I have imported STL geometry of two separate parts (bone and cartilage) into Hypermesh. There is slight overlap between the two parts, which results in the meshes overlapping when creating a mesh. I want the two components to have shared nodes at the interface such that the two components are 'merged' but are kept as separate components for the purpose of applying boundary conditions. I have previously used the faces panel to set equivalence between nodes for the component boundary, but this results in a bad mesh with poor element connectivity and free edges.
Recently, I used the solid edit panel with the boolean option to 'cut' one part with another. This appeared to result in good connectivity between the 2D meshes

You speak alot but without shared model, nobody can help.

Apologies, the forum doesn't give me permission to upload the .hm or .stl files. I've at least attached images of the issue.

Yes, some limitation of forum, but you have always Dropbox, Google Drive,... right?

we regret that there is no direct way to upload .hm files and simiilar files in the forum presently,
however apart from the workarounds suggested above, we can also upload .hm and similar files by renaming it .jpg and letting the forum members know it was renamed so.
One way could be to create tetra directly using 2d > shrinkwrap on the stl
