I'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
of the parts, but when I try to do a 3D mesh using the tetramesh panel, I get an error stating 'shell elem region incomplete' followed by '1 surfs failed and saved.'
Does anyone have any advice on how to accomplish meshing these two components while keeping the elements at their shared boundary 'merged'? Any assistance is greatly appreciated.
