Pseudo Time Stepping for Turbulent Flow Models
The default stationary solver applies pseudo time stepping for both 2D and 3D models. This improves the robustness of the nonlinear iterations as well as the condition number for the linear equation system. The latter is especially important for large 3D models where iterative solvers must be applied. The turbulence equations use the same
as the momentum equations.
The default manual expression for
