Detailed Description
template<typename Scalar>
class Hermes::Hermes2D::Form< Scalar >
Abstract, base class for any form - i.e. integral in the weak formulation of (a system of) PDE
By default, the form is initialized with the following natural attributes:
- no external functions.
- assembled over any (parameter 'HERMES_ANY') element/boundary marker.
Internal.

For time-dependent right-hand side functions. E.g. for Runge-Kutta methods. Otherwise the one time for the whole WeakForm can be used.

| void Hermes::Hermes2D::Form< Scalar >::set_ext | ( | MeshFunction< Scalar > * | ext | ) |
external functions - dual functionality with the overall WeakForm. For Agros, this approach is better in some way, for e.g. Euler equations, the other one (for the whole WeakForm) is faster.

External solutions for this form will start with u_ext[u_ext_offset] where u_ext[] are external solutions coming to the assembling procedure via the external coefficient vector.
