Description
Somehow `SampleMeshManager` seems to assign a boundary attribute of 1 to element boundaries in the domain. These are not a part of the boundary specified in the mesh. I think these are or 1) the element boundaries of the sample mesh or 2) elements on the boundary between partitions corresponding to MPI groups or 3) a combination of both.
I have verified that the boundary attribute is specified correctly in the input mesh and used correctly in the non-sampled (full order model) finite element space.
The result is that the boundary condition I have specified for boundary attribute 1 is applied randomly in the domain. I encountered this problem in a 3D problem and I did not see it in 2D problems (although it might be occurring there as well).
Is this a known problem? Ping @dylan-copeland
