Query: Parallel Element-based Algebraic Multigrid for H(curl) and H(div)
  Problems Using the ParELAG Library   This paper presents the use of element-based algebraic multigrid (AMGe)
hierarchies, implemented in the ParELAG (Parallel Element Agglomeration
Algebraic Multigrid Upscaling and Solvers) library, to produce multilevel
preconditioners and solvers for H(curl) and H(div) formulations. ParELAG
constructs hierarchies of compatible nested spaces, forming an exact de Rham
sequence on each level. This allows the application of hybrid smoothers on all
levels and AMS (Auxiliary-space Maxwell Solver) or ADS (Auxiliary-space
Divergence Solver) on the coarsest levels, obtaining complete multigrid cycles.
Numerical results are presented, showing the parallel performance of the
proposed methods. As a part of the exposition, this paper demonstrates some of
the capabilities of ParELAG and outlines some of the components and procedures
within the library.
