KNOWN ISSUE: Curvature correction implementation incorrect for two-equation turbulence models (Class 3 Error)
The implementation of the curvature correction coefficient for two-equation turbulence models is incorrect, with a curvature effect being predicted for flows that have no curvature if the coefficient (Cscale) does not have its default value of 1.0.
This is due to an error in the formulated equations for the curvature correction.
No workaround is currently available.
