FEIntegrator< _OriginalAssembler > Class Template Reference

Detailed Description

template<typename _OriginalAssembler>
class FEIntegrator< _OriginalAssembler >

Computes the integral of a quantity on the whole domain or subdomains, using a FE matrix.

The quantity to integrate is extracted from a distributed vector, which is passed at call. Attributes and unknowns can be given to the constructor to restrict the data to subdomains or given unknowns.

A matrix can be passed to calls to integrate if it has already been assembled
