I have problems with the .stl geometry rencently. I used SolidWorks to create
3D geometric models and then save them in .stl format as the mesh walls. However,
when I viewed the geometry with Paraview, they looked like solid. I noitced in the tutorial examples, all the geomery are surface mesh (please see the attached figures). the example.png is from the tutorial example, and the myexample.png shows my own example.
I failed to save plane/surface in the solidwork as .stl.
Does anyone know how to make surface mesh (not solid one) for the Liggghts. Thanks in advance for your expertise.
