  Hi, when I'm generating the surface mesh it kepts stucking at importing the CAD geometry using watertight geometry. It had generated the surface mesh last time, but it kept loading for about 30 mins this time. What's the problem here?

  Hi,
  I recommend you check the Ansys innovative course: Ansys Fluent Meshing Watertight Geometry Workflow - ANSYS Innovation Courses
  Thank you

  I'd look carefully at the minimum cell size, given I can't even see the marker I'd question how sensible a choice it is. The courses tell you how to use the code, the size markers (usually) tell you that you're about to overcook the cell count.

  I got the same problem : it gets stuck on “importing CAD geometry” for a couple hours.. I tried different sizings, same thing.. very weird

  Can you test a simple geometry? Just means we can eliminate the CAD readers and/or path as possible causes.
