  1. After making a modification to the design space definition of a component in my model, this resulted in changes to the solid geometry of the affected part and therefore surfaces separating the design space from non-design space could be removed and the associated surface edges could be suppressed. As a result, the component originally meshed as 2 solids (one for the design space and the other for the non-design space) now needs to be meshes as one solid. This specific part, however, shares faces with other components in the model that have already been meshed using tetras. In order to remesh the targeted component, while ensuring connectivity between the newly created elements and the pre-existing surrounding elements I attempted to extract the faces of tetra mesh where on the faces shared between the existing meshed solids and the part that I am looking to remesh. I am essentially left with a solid part that has a 2D mesh of TRIAS established on certain faces will others remain unmeshed. I want to automesh these remaining faces ad use a Volume Tetra to map the solid bounded by the surfaces.How do I do this while ensuring there is connectivity between the newly meshed faces and the pre-existing mesh,
  2. Hi, I have been trying to eliminate the element concentrations caused by HM 3D tetra remesh for a couple of months now and yet there is no robust solution available. I wonder if it is possible to extract a surface mesh from the 3D mesh components - for instance the front surface in attached pic and then remesh the surface mesh in a 2D manner. Later, after the new surface mesh is created, apply the 3D remesh feature to the entire mesh component basing on the new surface mesh. Would it be feasible in HM? How can I possibly extract the surface mesh and remesh it with certain "feature angle" parameter to filter out the wanted small segments? and can I use 3D tetra remesh with pre-defined 2D surface mesh? Answer to any of these questions would be most welcome. Many thanks, Wensong
