Class 3 Error

SYMPTOM:
A case using the transition model may give incorrect results and may incorrectly predict the transition location.

PROBLEM:
There is a coding error in the calculation of F_length (the length of the transition zone) as a function of the transition onset Reynolds number Re_theta_t, for values of Re_theta_t in the range of approximately 600 and 1200 (see the attached plot). This is expected to have little impact on mo


WORKAROUND:
No workaround is currently available.

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