Found a result control with faces that do not belong to the mesh. This may happen if the faces belong to a cell zone. Please remove these faces from the result control.
A result control item was assigned to a non-assignable face, that is, a face cannot be used for this purpose.
What Could Be the Possible Reason?
Result control items can only be assigned to faces that define boundaries in the mesh. In other words, faces where boundary conditions are (or can be) applied. This means that internal faces used to define cell zones (e.g., MRF rotating zone, porous media, or momentum source), can not be used for this purpose, because they do not create mesh boundaries.
What Can I Do Now?
You must remove the non-assignable face from the result control item assignment:
- Identify the cell zones created in your model, under Mesh > Cell Zones.
- Note the faces used to create the cell zones.
- Review your Result control items, to find which one of them is assigned to faces from cell zones.
- Remove the assignments from the invalid faces.
From the example shown in Figure 1, the blue cylinder is used to define a cell zone around the propeller. This cell zone is used to define the rotation of the propeller faces with a MRF model. In this case, all the faces of the blue cylinder are non-assignable to the result control items (nor boundary conditions), because those faces do not constitute mesh boundaries.
