Description

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

A high-level interface for a PDESolver.

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.

pure virtual

Solve the given PDE system (usually assemble + solve linear system + update)

Parameters

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

Implemented in Dumux::NewtonSolver< Assembler, LinearSolver, Reassembler, Comm >, and Dumux::NewtonSolver< Assembler, LinearSolver, DefaultPartialReassembler, Dune::Communication< Dune::MPIHelper::MPICommunicator > >.

solve() [2/2]

This is used for solvers that are allowed to e.g. automatically reduce the time step if the solve was not successful

Parameters
