Job Test MOOSE clang on efdaf92 : invalidated by @jwpeterson Unrelated failure of time_steppers/time_adaptive.test |
Ah, I think the failures I'm seeing from the unit tests are due to using a netCDF-4/HDF5 exo file... I think there is a way to convert it to something more portable to our CI, I just need to remember what that is... |

IIRC you can use h5dump to get ASCII out of the ExodusII-HDF5 file and pipe that to ncgen to put it into an ExodusII-NetCDF3 file. |
To do the conversion, first ncdump the file to text: ncdump foo.e > foo.txt Then ncgen with the -k '64-bit offset' option: ncgen foo.txt -k '64-bit offset' -o foo.e If not already in your PATH, the ncgen utility can be found in your libMesh build directory: $LIBMESH_BUILD/contrib/netcdf/v4/ncgen/ncgen

I don't think it will be easy to make #3851 work correctly in the short term, so this PR takes a different approach which is basically to just allow incomplete/incorrect neighbor information on meshes with multiple 1D Elems meeting in a single Node. To be clear, we were already doing this so the PR doesn't make it any worse, but we did have some overzealous asserts in
find_neighbors()which are currently being tripped when refining such meshes.
