A superconvergent HDG method for stokes flow with strongly enforced symmetry of the stress tensor Giacomini, Matteo; Karkoulias, Alexandros; Sevilla Cárdenas, Rubén; Huerta, Antonio (2018-12)
Open AccessThis work proposes a superconvergent hybridizable discontinuous Galerkin (HDG) method for the approximation of the Cauchy formulation of the Stokes equation using same degree of polynomials for the primal and mixed variables. ...
A superconvergent hybridisable discontinuous Galerkin method for linear elasticity Sevilla Cárdenas, Rubén; Giacomini, Matteo; Karkoulias, Alexandros; Huerta, Antonio (John Wiley & sons, 2018-10-12)
Open AccessThe first superconvergent hybridisable discontinuous Galerkin method for linear elastic problems capable of using the same degree of approximation for both the primal and mixed variables is presented. The key feature of ...
