CGSolver< number > Class Template Reference

This class exists as a hack to get access to the residual vector for the custom convergence criterion because dealii doesn't provide it for some reason. The function print_vectors gets called before the convergence check in the same scope and is overridable. Be careful, because the pointers are only valid during the linear solve, so they shouldn't be called outside of that context. More...

Detailed Description

template<typename number>
class CGSolver< number >

This class exists as a hack to get access to the residual vector for the custom convergence criterion because dealii doesn't provide it for some reason. The function print_vectors gets called before the convergence check in the same scope and is overridable. Be careful, because the pointers are only valid during the linear solve, so they shouldn't be called outside of that context.
