%AVERAGE_INT%

average of a functional based on all MESHFREE points with respect to given material flags

Average of a given functional \( f\) (ExpressionOfIntegrand) with respect to the set \( P\) of all MESHFREE points with given material flags:
\begin{align} I_{\text{Avg}} = \frac{1}{\#P} \sum_{i \in P} f_i,\end{align}
where \( \#P\) denotes the number of points in \( P\). Example:
begin_alias{} "Alias1" = " ... MAT$MaterialTag1$ ... " # definition of Alias1 "Alias2" = " ... MAT$MaterialTag2$ ... " # definition of Alias2 end_alias INTEGRATION($IntInd$) = ( %AVERAGE_INT%, ExpressionOfIntegrand, $MaterialTag1$, $MaterialTag2$ )

DROPLETPHASE

For DROPLETPHASE points, the parcel concept is automatically taken into account, so that
\begin{align} I_{\text{Avg}} = \frac{\sum_{i \in P} n_i \cdot f_i}{\sum_{i \in P} n_i}\end{align}
where \( n_i\) corresponds to the multiplicity stored in %ind_mult%.
