KNOWN ISSUE: Error when a temperature dependent source is added to a 1:1 Fluid-Fluid interface


SYMPTOM:
If a temperature-dependent source is added to a Fluid-Fluid interface whose Mesh Connection is set to 1:1, then the solver may generate the following messages during the calculation, but continue and generate an incorrect result:

Error in subroutine GET_TEMP_BELG :
Variable/locale undefined for BC type
GETVAR originally called by subroutine DEF_USR_SRC
Variable name: Temperature
Locale name: TilesSurface Side 1
BC physical type: PERIODIC
BC type: ZIF
Mesh Locale: BELG5
Mesh Entity: IP

PROBLEM:
This is due to a coding error in the CFX-Solver.

WORKAROUND:
Switch the Mesh Connection type to GGI.

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