Uniform block-diagonal preconditioners for divergence-conforming HDG Methods for the generalized Stokes equations and the linear elasticity equations

Fu, Guosheng; Kuang, Wenzheng

Abstract We propose a uniform block-diagonal preconditioner for condensed |$H$|(div)-conforming hybridizable discontinuous Galerkin schemes for parameter-dependent saddle point problems, including the generalized Stokes equations and the linear elasticity equations. An optimal preconditioner is...
