DIFFOP_kernel_Neumann
(chamberwise) factor for the weight kernel for the least squares approximation stencils for Neumann operators (UCV)
DIFFOP_kernel_Neumann = 5.0
Default: DIFFOP_kernel_Neumann = 2.0
The weight for the computation of the differential Neumann operators is given by
\begin{align}
W_{ij} = exp\left( -\alpha \cdot \frac{ \| {\bf x}_i-{\bf x}_j \|^2}{ \frac{1}{2}(h_i^2+h_j^2) } \right)
\end{align}
where alpha is equal to the value of DIFFOP_kernel_Neumann.
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.
