DIFFOP_Neumann_ExcludeBND
(chamberwise) parameter to exclude boundary points from the neighborhood for the computation of the Neumann operators (UCV)
DIFFOP_Neumann_ExcludeBND = 90.0
Default: DIFFOP_Neumann_ExcludeBND = -1.0 (do not exclude any boundary point from the neighborhood)
In order to exclude all neighbor boundary points from the stencil, set
A boundary point j is excluded from the Neumann stencil computation of point i, if the angle between the two boundary normals fulfills
\begin{align}
\left({\bf n}_i \sphericalangle {\bf n}_j\right) < \alpha
\end{align}
where alpha is the value of DIFFOP_Neumann_ExcludeBND, to be given in degrees.
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.
