EDIT: This has been turned into a feature request since the new way of disallowing a face to be both a slip wall and a symmetry plane always results in no-slip walls on the symmetry plane, if you use a symmetry plane.
The topic posts discuss the issue.
- I would like to be able to assign a face as a slip wall and a symmetry plane.
- I am OK if all my symmetry planes defined by faces are automatically (and permanently) set to no-slip walls.
A few months ago I ran many incompressible external simulations where my symmetry plane was also a face of the Background Mesh Box.
Now when I try to run a new simulation in those projects I get this error:
The face in question is a background mesh box face and it is my symmetry plane AND a slip wall.
If I can no longer use a background mesh box face as my symmetry plane, how do I assign a symmetry plane?
OR, do I even need a slip wall on the symmetry plane?
