I am trying to get a matched surface mesh at an interface between two different bodies and not able to get it working. This is to simulate heat transfer from molten metal to a crucible. I created the geometry as two parts, with one body in each part, in the design modeler. When I brought it to Meshing, I am able to get the correct interface under "Connections -> Contacts". But, when I generated the mesh, the surface meshes on those two bodies are different. Therefore, there are some gaps between the meshes (see the attached images). How do I get a matched surface mesh at the interface? I tried inserting "Mesh -> Insert -> Contact Match". But it didn't help.
I am using Version 19.1
