AdaptiveLinearVariationalSolver
(*args)¶ Bases:
dolfin.cpp.fem.GenericAdaptiveVariationalSolver
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.
