Detailed Description

template<class T, bool paramCoef = false>
class gismo::gsVisitorPoisson< T, paramCoef >

Visitor for the Poisson equation.

This visitor assembles the bilinear form

\[ ( \nabla u, \nabla v )_\Omega \]

and simultainously the linear form

\[ ( f, v )_\Omega, \]

where \(u\) is the trial function, \(v\) is the test function and \(f\) is the right-hand-side function.
