When going through the ball valve tutorial the instructions direct you to set the "Smallest Flow Passage" to 9.3mm.
How is this determined? How do I know what to set this value to my own models?
How would increasing or decreasing this dimension affect the model?
And what is the profile of this 9.3mm opening? cylindrical? Is it the major or minor dimension of an oblong opening?
...Or is this the mesh size?
