class dolfin.fem.adaptivesolving.AdaptiveLinearVariationalSolver(problem, goal)

A class for goal-oriented adaptive solution of linear variational problems. For a linear variational problem of the form: find u in V satisfying

a(u, v) = L(v) for all v in :math:\hat V


and a corresponding conforming discrete problem: find u_h in V_h satisfying

a(u_h, v) = L(v) for all v in :math:\hat V_h


and a given goal functional M and tolerance tol, the aim is to find a V_H and a u_H in V_H satisfying the discrete problem such that

\|M(u) - M(u_H)\| < tol


This strategy is based on dual-weighted residual error estimators designed and automatically generated for the primal problem and subsequent h-adaptivity.
