A Scalable Deflated Conjugate Gradient Solver for the Time-Dependent Pseudo-Stress Stokes Problem
Alessandra Cancrini, Gabriele Ciaramella, Paola F. Antonietti
We propose a novel iterative solution framework for the unsteady Stokes equations in the pseudo-stress formulation. When solving this class of problems by using implicit time-integ…

A polytopal discontinuous Galerkin method for the pseudo-stress formulation of the unsteady Stokes problem
Paola F. Antonietti, Michele Botti, Alessandra Cancrini +1
This work aims to construct and analyze a discontinuous Galerkin method on polytopal grids (PolydG) to solve the pseudo-stress formulation of the unsteady Stokes problem. The pseud…
