Description

template<class A, class LS>
class Dumux::PDESolver< A, LS >

A PDESolver is constructed with an assembler and a linear solver and has a method solve that linearizes (if not already linear), assembles, solves and updates given an initial solution producing a new solution.

apply()

template<class A , class LS >

virtual bool Dumux::PDESolver< A, LS >::apply ( Variables &  vars )

pure virtual

Parameters

vars	instance of the Variables class representing a numerical solution, defining primary and possibly secondary variables and information on the time level.

Returns

bool true if the solver converged

Postcondition

If converged, the given Variables will represent the solution. If the solver does not converge, it may be the case that they are in some intermediate (implementation-dependent) state.
