Integrate a GridFunction.
\code
#include <dune/pdelab/common/functionutilities.hh>
Integrate a GridFunction over the domain given by the GridFunction's GridView. In the parallel case, this function integrates over the Interior_Partition only. If the accumulated result over all processors result is required, use something like
integrateGridFunction(gf, sum);
sum = gf.getGridView().comm().sum(sum);
- Template Parameters
-
GF Type of the GridFunction.
- Parameters
-
gf The GridFunction object. sum Resulting integral. There is no need to clear this variable before calling this function. qorder Quadrature order to use. If the GridFunction is element-wise polynomial, then this is the order of the highest-order monom needed to represent the function.
