FAVOR error
 

Hello, new user here.

I am trying to check my model mesh using FAVOR, but when I click Render, I get an error message that reads, "No FAVOR surface of the geometry has been created."

Can someone explain what might cause this message to appear?

I had a pipe/shaft configuration with walls that were too thin. This was resolved by drawing the internal volume of the pipe/shaft as a solid and using its complement.
