SYMPTOM:
Non-MeTiS methods (eg, user-specified direction) can give poor partitions on structured grids, if the distance of an entire plane of nodes is the same in the specified direction. The partition boundary can be jagged, switching back and forth between two planes. This can lead to excessive overlap and possible robustness problems (particularly with free surface flow).
PROBLEM:
This is due to this potential problem not being thought of during design.

WORKAROUND: There is no workaround. FIXED IN: ANSYS CFX Release 11.0 Update 1. |
