meshing only the big domain covering the small one

Please login with a confirmed email address before reporting spam

There are two domains in a model . The smaller domain is a real subset of the bigger. In other words, the big domain entirely covers the small one. The two domains form a union. Is there any way to mesh the whole model so that the mesh only considers the big domain as if there were no small domain? In other words, there is no need to refine the mesh at the boundary between the two domains.

Maybe you could send a sketch of what you would like to achieve? If you do not need the smaller domain for meshing, the question is why do you include it at all? If you simply want to disregard the small domain, why do you need to get a union? An assembly would be just fine to mesh one or the other domains (or both of them) with completely separate meshes, that you can reconnect if needed with non-local coupling variables at the physics level). A sketch would help to understand your need. Take care, Eric Favre

In Mesh there is 'Delete Entities' and in Geometry there is 'Virtual Operations' to remove all kind of entities.

With Mesh Plot and Filter or a Clip Plane you can see the inner result.
