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.

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 functions. Set one external function.

Internal - this structure is being filled anew with every assembling. True iff areas contain HERMES_ANY - meaning that this form represents an integral over the whole domain (whole boundary in case of surface forms).

When dealing with nonlinear problems of multiple equations, sometimes the nonlinearity has to access different quantity previous iterations. This selector servers for that purpose - according to this, the correct one will be selected - see e.g.DefaultJacobianDiffusion class. Defaults to 'i' for VectorForm and 'j' for MatrixForm. This can be changed in derived forms.

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.
