Class 3 Error
If the turbulence control option is used in the global dynamic model control functionality, the CFX Solver may fail in several ways depending upon the turbulence model. It may give a memory management error like:
Error detected by routine PSHDIR
CDRNAM = FL1 /TURBM/TKE
CRESLT = NONE
Current Directory : /FLOW/PHYSICS/ZN1
However, for the k-epsilon turbulence model (and perhaps others), the Solver does not fail, but gives a zero equation turbulence model solution to the momentum equations, even though the k and epsilon equations themselves are solved, so that it looks as though the solution is progressing well.
This is due to an error in the s
Do not use the dynamic turbulence control, which should be unnecessary, or restart after the point of transition.
