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.
