Description

template<class Assembler, class LinearSolver>
class Dumux::LinearPDESolver< Assembler, LinearSolver >

An implementation of a linear PDE solver.

Template Parameters

Assembler	the assembler
LinearSolver	the linear solver
Comm	the communication object used to communicate with all processes

Note

If you want to specialize only some methods but are happy with the defaults of the reference solver, derive your solver from this class and simply overload the required methods.
