KNOWN ISSUE: Pitch angle calculation incorrect when initial mesh spans the theta = pi plane (Class 3 Error)
SYMPTOM: The CFX-Solver may calculate the pitch angle incorrectly when the initial mesh spans the plane where the theta coordinate is equal to pi (or -pi). PROBLEM: The new pitch calculation algorithm does not properly check and correct for this scenario. WORKAROUND: The pitch calculation can be reverted to use the old algorithm by setting the expert parameter "ggi dtheta mode = 1". FIXED IN: ANSYS CFX Release 12.1. A custom executable for ANSYS CFX Release 12.0 is available on request. |
