  • Abstract
    The algebraic multigrid (AMG) method is an efficient preconditioner for large-scale finite element analyses. However, in edge-element analyses, the large null space of the coefficient matrices causes difficulties in applying AMG techniques. Here, we present a new AMG preconditioning for edge-element analyses. Numerical results demonstrate a promising performance for our proposed preconditioner
