Detailed Description

template<typename Scalar>
class Hermes::Hermes2D::WeakForm< Scalar >

Represents the weak formulation of a PDE problem.

The WeakForm class represents the weak formulation of a system of linear PDEs.
The number of equations ("neq") in the system is fixed and is passed to the constructor.
The weak formulation of the system A(U, V) = L(V) has a block structure. A(U, V) is
a (neq x neq) matrix of bilinear forms a_mn(u, v) and L(V) is a neq-component vector
of linear forms l(v). U and V are the vectors of basis and test functions.

There is a single tutorial just on implementing the weak formulation.
For some basic ideas, please see the examples provided.
