Hey Dominic,
thank you for your answer. I am solving the Richards Equation (nonlinear
PDE) with the DG method, essentially using:
typedef Dune::PDELab::QkDGLocalFiniteElementMap<Real,Real,order,dim>
FEM; as finite element map,
typedef Dune::PDELab::ISTLBackend_BCGS_AMG_SSOR<IGO> LS; as linear
solver,
typedef Dune::PDELab::Newton<IGO,LS,U> PDESOLVER; as non-linear solver,
Dune::PDELab::Alexander2Parameter<Real> alex2; as timestepper.
The grid is set up with
Dune::FieldVector<double,dim> N;
for (unsigned int i=0; i<dim; i++)
N[i] = elements[i];
Dune::FieldVector<bool,dim> periodic(false);
int overlap = 2;
const YaspXDirPartition<dim> yp;
Dune::YaspGrid<dim>
grid(helper.getCommunicator(),upperRight,N,periodic,overlap,&yp);
typedef Dune::YaspGrid<dim>::LeafGridView GV;
const GV& gv=grid.leafGridView();
I have appended the source code responsible for the actual solution,
along with two logfiles - one with barely over 2000 elements in the
grid, one barely below. You can see that the amount of linear iterations
(and thus linear solve time) rises sharply if the elements exceed 2000.
I hope this is enough information to address this problem - if not,
please tell me so.
Thank you kindly for your time!
Dion
