Hello,
I have a 1D radial mode porous flow simulation implemented via
Dune::YaspGrid<1, Dune::EquidistantOffsetCoordinates<double, 1> >
and
struct GGTraits : public BoxDefaultGridGeometryTraits<GridView>
{ using Extrusion = RotationalExtrusion<0>; };
I am using the Box method. My program works well when ran as single.
With MPI, however, I get the following message from fvassembler.hh:
Warning: norm calculation adds entries corresponding to
overlapping entities multiple times. Please use the norm
function provided by a linear solver instead.
and the solver does not converge because the residual does not change.
I am seeking advice.
Best regards,
Dmitry
