Advantages of static condensation in implicit compressible Navier–Stokes DGSEM solvers

“…However, in our case for the GL-DGSEM of the compressible Navier-Stokes equations, the number of non-zeros increases. Increased number of non-zeros for the condensed system have been reported by Habchi [46], for an elastohydrodynamic lubrication problem. There, the authors considered several meshes for the same contact problem, from extra coarse to extra fine.…”
