Class 3 Error

SYMPTOM:
If a particle transport calculation is run in parallel, then particles may bounce off the stage interface rather than continuing from a random circumferential position with the same radial and axial positions. This may not be noticed if all the tracks are not plotted and studied carefully in CFX-Post.

PROBLEM:
The CFX Solver incorrectly calculates control surface numbers for the particles as they cross the sta


WORKAROUND:
Run the case in serial mode, if possible.

FIXED IN:
ANSYS CFX Release 12.0. A custom executable for ANSYS CFX Release 11.0 SP1 is available on request.
