Detailed Description

Represents the weak formulation of a 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.
