Class 3 Error
SYMPTOM:
This error applies to two distinct setups.
1) A case run in parallel with stage interfaces may have errors in the calculation of the stage averaged pressure and the stage mass flow.
2) A case run in parallel when the mass flow rate is specified at a GGI Interface boundary may have errors in the calculation of the mass flow.
In most cases the error will not occur or will be small.
PROBLEM:
The CFX Solver makes an assumption that each GGI control surface is contained within the same partition as the corresponding face on the first interface side. This is not always true. In this case in a parallel run the CFX Solver will miss some of the control surfaces when building the averaged stage group pressure and the summarized stage group mass flow, or when the mass flow rate is calculated at GGI Interfac

WORKAROUND: No workaround is available. FIXED IN: ANSYS CFX Release 12.0. A custom executable for ANSYS CFX Release 11.0 SP1 is available on request. |
