We present a static-condensation method for time-implicit discretizations of the Discontinuous Galerkin Spectral Element Method on Gauss-Lobatto points (GL-DGSEM).  ...  To test it we solve the compressible Navier-Stokes equations with direct and Krylov subspace solvers, and we show for a selected problem that using the statically condensed GL-DGSEM leads to speed-ups  ...  This work was supported by a grant from the Simons Foundation (#426393, David Kopriva).

Fourier spectral/hp element method: investigation of time-stepping and parallelisation strategies

Alessandro Bolis, Spencer Sherwin, Engineering And Physical Sciences Research Council
<span title="2015-07-17">2015</span>
This thesis focuses on algorithm optimization, to minimize run-time, when solving the incompressible Navier-Stokes equations.  ...  We initially describe the building blocks of a spectral/hp element and pure spectral method and how they can be encapsulated and combined to create a 3D discretisation, the Fourier spectral/hp element  ...  a static condensation approach.  ...
