There seems to be a bug inside SPR routines, that causes the successively adapted meshes to not converge for some examples. For example, attached is a picture of adaptive-solve (with MFEM and PUMI) for a linear elasticity problem on the upright model. In this picture going from the 1st adapted mesh (middle mesh in the top row) to the 2nd adapted mesh (right mesh in the top row), the mesh gets coarsened a lot.

The following picture shows the recovered fields (computed inside SPR routines) on the same meshes. Note the extremely high value of the recovered field on the 1st adapted mesh (middle mesh in the top row).

I think this may have been an off-by-one error. SCOREC/mfem@2d055eb

That could be the case.
