Class 3 Error
SYMPTOM:
When calculating a laminar flow, if one creates partial trn files including the wall shear stress, then this stress will have the wrong sign. Thus forces in CFX-Post will be
calculated as pressure force minus shear force instead of pressure force plus shear force. This does not affect res files or full trn files, when a different algorithm is used
to calculate the stress and force.
PROBLEM:
This is due to a bug in the CFX Solver in calculating the shear stress
|
WORKAROUND: The workaround is to use a full trn file if sufficient disk space is available. FIXED IN: Release 11.0. Custom executable for Release 10.0 available on request. |
