great input! This is something that will be possible moving forward - right now, a similar workflow can be achieved but the mesh is computed each time entirely. How you would do this right now is - say, you’re looking into generating a tet-mesh with certain refined regions. So you’d use the “Tet mesh with refinements” operations without any local refinements and then generate it. Once generated, you could see the overall mesh fineness. Once you’re happy with that, you add local refinements to the same mesh operation and re-run it. This will recompute the mesh with your added refinements. So that way you can work iteratively as well, but each time on the same operation.
We’re right now working on improving the overall meshing workflow, where similar concepts as you explained are currently being considered.
Hope this helps for your current work!
