Class 3 Error

SYMPTOM:
When heating a Homogeneous Binary Mixture containing a liquid and gas phase, and where the gas phase Specific Heat Capacity is defined in NASA polynomial format, the temperature of the mixture is correct as long as some liquid is present. However, when all the liquid has evaporated the addition of more heat does not increase the temperature of the vapour.

PROBLEM:
This is due to a bug i


WORKAROUND:
Re-formulate the NASA material Specific Heat Capacity in terms of CEL expressions.

FIXED IN:
ANSYS CFX Release 12.0. A custom executable for ANSYS CFX 11.0 SP1 is available on request.
