Detailed Description

template<class F>
class hp2D::BilinearFormHelper_2_2< F >

Helper class for bilinearforms a(u,v), where u and v are 2-forms.

\[\displaystyle a(u,v) = \int\limits_K f(\underline{x})u(\underline{x})v(\underline{x})\,dx = \int\limits_{\hat{K}} \hat{u}(\xi)\,\circ F_K^{-1}\hat{v}\,\circ F_K^{-1}f(F_K(\xi))\det J^{-1}\,d\xi\]

J is the Jacobian matrix.

Computes intermediate data for element matrix computation.
