static double Dune::Fem::GridWidth::calcGridWidth ( const GridPartType &  gridPart, const bool  communicate, const MinMax &  minmax  )

inlinestatic

calculate minimal grid width as \(h_{E} :=\frac{|E|}{h^{E}_{m}}\) with \(h^{E}_{m} := \min_{e \in \mathcal{I}_{E}} |e| \).

Parameters

gridPart	set of element the minmal with is calculated for
communicate	do global communication to get minimal width for all processes (default = true)
minmax	Function which switches between the overall minimun and maximum
