Summary: Enables a more accurate method of solving for the pressures and velocities and temperature near no-slip walls in conjunction with the SST turbulence model.

sst_new_iwf A
A = 1: (On) = Enables the slip-wall formulation for the momentum and energy equations on boundaries where Dirichlet conditions are applied.
A = 0: (Off) = Disables the slip-wall formulation. (Default)
Description
The new IWF (slip-wall) formulation is a more accurate method of solving for the pressures and velocities and temperature near no-slip walls. It correctly implements the near wall aspects of the SST turbulence model. The condition is applied only to walls where the velocities (or temperature) are prescribed as fixed.
This flag only works in the context of the SST turbulence models and its variants (DES, SAS).
