[MOAB-dev] ghost exchange with triangles?

[Ryan O'Kuinghttons]

Hi Iulian, I ran into an issue with the ghost element exchange this 
week. I'm using a small test mesh with one quadrilateral, two triangles 
and two pentagon/hexagons that are broken down into triangles. The ghost 
exchange seems to work, but the tag exchange does not. I modified the 
test we were using before, if you want to have a look. When I plot the 
mesh after the exchange_tags call I see 0s at the the node and element 
ids locations, which is strange because this works just fine with a mesh 
of quadrilaterals. The test is on the moab4 branch, at 
esmf/src/Infrastructure/Mesh/tests/ESMC_MeshMOABGhostUTest. You should 
call 'make distclean' before rebuilding esmf, then just "make" in test 
directory and you can run it with:

mpirun -np 4 $ESMF_DIR/tests/*/*/ESMC_MeshMOABGhostUTest

I am traveling today, and I will be in and out most of the day, but will 
check email when I can. I have a feeling this is another issue with how 
we are setting the tags, but hopefully it's a quick fix. Thanks again,
