Class 3 Error
Stage Interfaces in combination with Pitch Change = None can be set up in CFX Pre and in the CFX Solver without error. The solution at the interface, however, often exhibits a single, large circumferential band (typically taking up 90% or more of the interface) where several may be expected.
This is due to a coding error in the CFX Solver, and a missing check in CFX Pre. The large circumferential band is a symptom of the fact that the CFX Solver is unable to create the bands for zero Pitch Change. Stage Interfaces should not be allowed in combination with no
No workaround is currently available.
