GASDYN_Upwind_Lgamma
(chamberwise) GASDYN parameter for FPM1 and FPM3
GASDYN_Upwind_Lgamma = 0.2 # 0.2*H as upwind step size
Default: GASDYN_Upwind_Lgamma = 0.0 (no upwind)
GASDYN_Upwind_Lgamma represents the parameter \( \gamma\) in GeneralizedUpwind.
Additional feature:
By putting a minus-sign in front, i.e. GASDYN_Upwind_Lgamma = -A, then we have
\begin{align}
\gamma = \left\{ {\begin{array}{*{20}{c}}
{0 {\text{ }}if{\text{ }}\nabla ^T{\mathbf{v}} > 0{\text{ (rarefaction)}}}\\
{abs(A) {\text{ elsewise }}}
\end{array}} \right.
\end{align}
Note: This parameter can also be set chamberwise for multiphase simulations (see also KindOfProblem, CHAMBER).
If it is not set for specific chambers, it is automatically set according to the non-chamberwise definition for all chambers.
