turn_down_BND_order
(chamberwise) parameter to automatically reduce the approximation order of a boundary point
Default:
turn_down_BND_order = 0.25
The approximation order of a boundary point (including free surfaces!) is automatically reduced by one,
if the ratio between number of interior and boundary points in the stencil fulfills
\begin{align}
\frac{N_{interior}}{N_{boundary}} <= TurnDownBNDorder
\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.
