How to work with STL file?

      How can I import and use STL files with ANSYS Simulation products?

      The best way to work with STL files is to import the STL file into ANSYS Spaceclaim and then convert into a CAD geometry file such a Parasolid. The CAD geometry can then be used by ANSYS Mechanical and other ANSYS simulation products. 


      Note that generally *.STL files are not able to capture geometry appropriately and ANSYS Spaceclaim helps to repair the .STL file if needed.

      It is best to import STL files into ANSYS Spaceclaim and export them as CAD geometry files such as Parasolid files.It is the best way to do this task.

      I would be grateful for your assistance on this occasion.

      I have meshed a STL file in Ansys ICEM. It is a complex geometry. When I import the mesh in Fluent for CFD analysis, I keep receiving the same warning message despite my attempts to review the mesh in ICEM. Here is the warning message:

      Building...

      mesh

      Error: Build_Grid: no faces in case file.

       

      Clearing partially read grid.

       

      Error: Build Grid: Aborted due to critical error.

       

      Error: Build Grid: Aborted due to critical error.

      Error Object: #f

       

      Where am I going wrong?

      I can share my file on a teams or zoom call in order to exchange an opinion and advice.

       

      Kind Regards
