SYMPTOM:
A Definition File, created by importing a mesh generated with the Patch Independent Mesher, fails in the CFX-Solver with the following error:
+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| REDHDR: locating dataset failed: what=G/NFC where=ZN1 |
| |
| |
| |
| |
| |
+--------------------------------------------------------------------+
No errors are reported during the import of the mesh into CFX-Pre, or when the Definition File is written.
PROBLEM:
This issue can occur with the Patch Independent meshing feature in the Meshing Application, but in principle could also occur with other ANSYS meshers if geometry de-featuring is enabled.
The fundamental problem is that the patches for the mesh model do not match up with the regions in the CAD model. In particular there are regions in the CAD model that do not have any mesh associated with them. During the translation of the mesh from the Meshing Application to CFX, these regions should be skipped but are not due to a bug. As a result the intermediate GTM file contains regions with no associated mesh.

WORKAROUND: No workaround is currently available. FIXED IN: ANSYS 11.0 SP1. A custom library is available on request. |
