Summary: Stabilization for rotating and compressible analyses.
Flag
use_bl_stabilization A
A = 0: Default behavior in which the stabilization is only used for models with rotating regions and ADV 2.
A = 1: Uses the stabilization is in all cases if you are running flow and have more that one enhancement layer.
A = 2: Disables the flag
Description
Some rotating and compressible analyses are prone to non-physical high-velocity “jetting” in the boundary layer regions. This algorithm reduces this behavior and improves stability and accuracy.
It is enabled automatically for rotating region analyses that have mesh enhancement enabled.
