[Libmesh-users] p-refinement for Lagrange variables?

[David K. <dav...@ak...>]

I'm using LAGRANGE variables for an elasticity problem and I'd like to be
able to increase the variable order from 1 to 2 specified elements. Is it
possible to do this using p-refinement in libMesh?

I had a vague impression that p-refinement was only supported for
discontinuous or hierachic basis functions, but from looking at the
fe_lagrange*.C code it seems that it does use elem->p_level(), so I wanted
to check if libMesh already handles this case? If so, does it automatically
constrain with hanging nodes on the interface of first and second order
elements (I guess this is almost the same as AMR so maybe it's already
supported)?

Thanks,
David
