Class 3 Error
When either of the ray-tracing radiation models in CFX (Discrete Transfer or Monte Carlo) is used in conjunction with any moving mesh /sliding mesh feature (e.g. transient rotor stator), then the solution may be incorrect if any non-overlap region changes position or extent during the course of the calculation.
This is due to the fact that the ray-tracing non-overlap data structures in the solver are not updated to account for the change in non-ove
No workaround is currently available.
