GASDYN_Upwind_Lbeta

(chamberwise) GASDYN parameter for FPM1 and FPM3

GASDYN_Upwind_Lbeta = 0.5 # second order time integration
Default: GASDYN_Upwind_Lbeta = 0.0 (first order time integration) GASDYN_Upwind_Lbeta represents the parameter \( \beta\) in GeneralizedUpwind. Additional feature: By putting a minus-sign in front, i.e. GASDYN_Upwind_Lbeta = -A, we have \begin{align} \beta = \left\{ {\begin{array}{*{20}{c}} {abs(A) {\text{ }}if{\text{ }}\nabla ^T{\mathbf{v}} > 0{\text{ (rarefaction)}}}\\ {0{\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.
