Hi Georg,
the piece of code looks fine to me. Assuming that it really is, the
problem has to be outside:
- the value of anodeChannelGDLInterface_ might be wrong
- the mdGrid does not contain the upper and lower parts
Kind regards

Hello DuMuXers,
The grid geometry I want to create is attached as .jpg-file. I want to
create a sub domain Omega1 as depicted. Here is my code from the
coupled problem:
void initializeGrid()
{
MDGrid& mdGrid = this->mdGrid();
mdGrid.startSubDomainMarking();
// subdivide grid into three subdomains
ElementIterator eendit = mdGrid.template leafend<0>();
for (ElementIterator elementIt = mdGrid.template leafbegin<0>();
elementIt != eendit; ++elementIt)
{
// this is required for parallelization
// checks if element is within a partition
if (elementIt->partitionType() != Dune::InteriorEntity)
continue;
GlobalPosition globalPos = elementIt->geometry().center();
if (globalPos[0] < interface12_)
{
if(globalPos[0] < anodeChannelGDLInterface_) // add
everything
mdGrid.addToSubDomain(anode_,*elementIt);
else
if(globalPos[1] < noPEMUpper_ && globalPos[1] >
noPEMLower_) // add only the middle part
mdGrid.addToSubDomain(anode_,*elementIt);
}
else{
if (globalPos[0] > interface23_)
mdGrid.addToSubDomain(cathode_,*elementIt);
else
{
if (globalPos[1] < noPEMUpper_ && globalPos[1] >
noPEMLower_)
mdGrid.addToSubDomain(pem_,*elementIt);
}
}
}
mdGrid.preUpdateSubDomains();
mdGrid.updateSubDomains();
mdGrid.postUpdateSubDomains();
gridinfo(this->sdGrid1());
gridinfo(this->sdGrid2());
gridinfo(this->sdGrid3());
}
What I obtain is a rectangular Omega1 bounded by noPEMUpper_,
noPEMLower_ and interface12_. The upper and lower part left of
anodeChannelGDLInterface_ are not part of the grid. Anyone has a clue
why this is not working?
Best regards
Georg Futter
