Class 3 Error

SYMPTOM:
Transient calculations that include transported Additional Variables through porous domains do not give the correct solution for the Additional Variable. Typically in regions of porosity, the Additional Variable values are not affected by flow acceleration/deceleration due to the volume restriction.

PROBLEM:
This is due to a bug in the CFX Solver. The transient term in the transport equation for Additional Variables does not include the effect


WORKAROUND:
No workaround is currently available.

FIXED IN:
ANSYS CFX Release 11.0 Service Pack 1.
