This paper presents the use of element-based algebraic multigrid (AMGe)hierarchies, implemented in the ParELAG (Parallel Element AgglomerationAlgebraic Multigrid Upscaling and Solvers) library . It produces multilevelvelpreconditioners and solvers for H(curl) and H(div) formulations . This paper demonstrates some of the capabilities of the library and outlines some of its components and procedures . The results are presented, showing the parallel performance of the proposed methods .
