Stabilized Continuous and Discontinuous Galerkin Techniques For
We design stabilized methods based on the variational multiscale decomposition of Darcy’s problem. A model for the subscales is designed by using a heuristic Fourier analysis. This model involves a characteristic length scale, that can go from the element size to the diameter of the domain, leading to stabilized methods with different stability and convergence properties. These stabilized metho...
متن کاملA stabilized mixed discontinuous Galerkin method for Darcy flow
A new mixed, stabilized, discontinuous Galerkin formulation for Darcy flow is presented. The formulation combines several attributes not simultaneously satisfied by other methods: It is convergent for any combination of velocity and pressure interpolation higher than first-order, it exactly satisfies a mass balance on each element, and it passes twoand three-dimensional constant-flow ‘‘patch te...
متن کاملMixed Discontinuous Galerkin Methods for Darcy Flow
We consider a family of mixed finite element discretizations of the Darcy flow equations using totally discontinuous elements (both for the pressure and the flux variable). Instead of using a jump stabilization as it is usually done for DG methods (see e.g. [3], [13] and the references therein) we use the stabilization introduced in [18], [17]. We show that such stabilization works for disconti...

متن کاملA Hybrid Discontinuous Galerkin Method for Darcy-Stokes Problems
We propose and analyze a hybrid discontinuous Galerkin method for the solution of incompressible flow problems, which allows to deal with pure Stokes, pure Darcy, and coupled Darcy-Stokes flow in a unified manner. The flexibility of the method is demonstrated in numerical examples.
