Class 3 Error

SYMPTOM:
If you have more than one fluid and you specify Cartesian velocity components for a specific fluid on an Opening boundary condition, then the simulation results may not be what you expect.

PROBLEM:
Fluid-specific Cartesian velocity components on openings are always applied in the rotating frame of reference, regardless of the Frame Type specified for the bounda


WORKAROUND:
Specify the velocity components in the rotating frame of reference.

FIXED IN:
ANSYS CFX Release 12.0.1. A custom tt.txt fix for ANSYS CFX Release 11.0 Service Pack 1 is available on request.
