In creating swept meshes, I've encountered the "Unsupported topology of linking face" error message. This drove me crazy for months. I finally figured out the cause: The "linking faces" are those connecting the source face to the destination faces. In my model, some of those faces weren't continuous from src to dst--they were divided by an edge, as COMSOL often does with revolved surfaces. Simply healing each divided surface into a continuous one, for example with a Form Composite Face or Ignore Edge operation, resolved the meshing error. Voila!
