%SUMMATION_BND%

summation of given function values based on all MESHFREE boundary points with respect to given boundary elements

Summation of a given functional $ f$ (ExpressionOfIntegrand) with respect to the set $ P_\text{BND}$ of all MESHFREE boundary points with given POSTPROCESS-flags:

\begin{align} I_{\text{SumBND}} = \sum_{i \in P_\text{BND}} f_i\end{align}

Example:

begin_alias{} "Alias1" = " ... POSTPROCESS$PostprocessTag1$ ... " # definition of Alias1 "Alias2" = " ... POSTPROCESS$PostprocessTag2$ ... " # definition of Alias2 end_alias INTEGRATION($IntInd$) = ( %SUMMATION_BND%, ExpressionOfIntegrand, $PostprocessTag1$, $PostprocessTag2$ )
