KNOWN ISSUE: Transient multiphase flow with Total Energy heat transfer model (Class 3 Error)


SYMPTOM:
When doing a transient multiphase simulation using the Total Energy heat transfer model, there is an error in the discretization of the transient pressure term in the energy equation.

PROBLEM:
The volume fraction is inside the time derivative, but it should be outside.

WORKAROUND:
No workaround is currently available.

FIXED IN:
ANSYS CFX Release 14.0. A custom executable for ANSYS CFX Release 13.0 is available on request.
