Actually, it might work also for ALUGrid
if DUNE_GRID_EXPERIMENTAL_GRID_EXTENSIONS is set to _false_ because
that triggers the default behavior of boundaryFlag().

Martin is right about the boundaryId. I guess that means it doesn't
work with ALUGrid like this at the moment. For other grids,
scvf.boundaryFlag()
should return the boundarySegmentIndex, so
gridData->getBoundaryDomainMarker(scvf.boundaryFlag())
should return the right thing. Are you bound to ALUGrid or can you
try with UGGrid?
Apart from that, we should see how to make things consistent.
Kind regards
Bernd

Hi Samuel,
maybe I am wrong but the scvf.boundaryFlag() returns the boundaryId
of AluGrid which is only properly defined if you are using a DGF grid
file.
The CO2 test uses such a DGF file, which is why it works there.
Maybe having a look at the tests in test/io/gridmanager helps.
Best regards,
Martin

Hi Timo, Hi Bernd,
thanks a lot for your help.
I'm compiling the dune modules with the cmake.opts in the dumux
repository, which contains "-
DDUNE_GRID_EXPERIMENTAL_GRID_EXTENSIONS:BOOL=True" in
"CMAKE_FLAGS", so
I assume that I don't need any additional changes.
The problem file in co2/implicit looks like what I need. However,
when
using scvf.boundaryFlag() I always get the same value, 1, but when
I
instead loop over all interfaces of the current element and use the
'getBoundaryDomainMarker'-function I do get the values I expect.
I'm using the gmsh mesh-format version 2.2 and ALUGrid. Do you know
what might be going wrong here?
Best regards,
Samuel

Hi Samuel,
as an addition to Bernd's answer, you might have to set
DUNE_GRID_EXPERIMENTAL_GRID_EXTENSIONS:BOOL=TRUE
for compiling dune-grid and the grid modules. I'm not sure if this
is
still required.
Best wishes
Timo

Hi Samuel,
I think that it is given by scvf.boundaryFlag(). Have a look at

Betreff: [DuMuX] How to get intersections from scvf and element?
Hi Dumux people,
I'm currently trying to use a grid generated with gmsh and would
like
to set the boundaries based on BoundaryDomainMarkers.
I found that it's possible to access the boundary domain markers
via
the function 'getBoundaryDomainMarkers', which accepts either a
Intersection or a boundary segment index as argument.
How do I now get the intersection/boundary segment index when I
have a
given element and scvf, e.g. inside the 'neumann' function
(solution
dependent neumann boundary)?
Best regards,
Samuel
