I'm using Netgen for FEA (shameless plug: Mecway - easy to use FEA) and it would be extremely useful to be able to do this. Ideally it would happen automatically through OCC if the CAD model has multiple parts joined together.
Possibly an easier way would be to allow the user to define the surface mesh to be used on one surface but have the rest generated by Netgen. In this way, you could first mesh one part in the usual way, then take the mesh on the interface surface and use that to constrain the meshing of the 2nd part.
I've done a little work with the Netgen code but can't see how to achieve this - though it sounds like it should easy.
I am also trying to do this job.I think the step should be like this:project the elements of one face to another,and then mesh another face with the preview elements as constraint condition.
I am also interested in the same type of mesh generation.
Do you have any progress in meshing?
