Dear libMesh users and developers,
I hadnt remembered to
send these changes to Ben, please note these additional changes:
Steady-state (fully coupled or single-physics) problems:
1) Adjoint refinement based error estimators (Global bounds for | Q(u) -
Q(u_h) |, adjoint example 4)
2) Adjoint refinement based error indicators (adjoint example 4)
3) A new adjoint example 3 that illustrates the use of the new Weighted
Patch Recovery Error Indicator in conjuction with adjoint based mesh
refinement, for a coupled, nonlinear problem.
Thanks.
