KNOWN ISSUE: Parallel moving mesh calculations with domain interfaces (Class 3 Error)
|
SYMPTOM: In a parallel moving mesh calculation in which a partition boundary intersects a domain interface, and there are no periodic boundaries or symmetry planes, it is possible for the CFX-Solver to give incorrect answers, due to the geometry not updating correctly. This will often be reflected in the non-overlap fraction at the interface increasing with time, but it is possible for the non-overlap fraction to stay small with an incorrect answer. PROBLEM: This is caused by a lack of communication of the 'Conservative Interface Flux' condition for the mesh displacement on interfaces at partition boundaries. WORKAROUND: If possible, use alternative partitioning methods so that the domain interface and partition boundaries do not intersect. FIXED IN: ANSYS CFX Release 12.1. A custom executable for ANSYS CFX Release 12.0 is available on request. |
