Optimal pressure approximation for the nonstationary Stokes problem by a variational method in time with post-processing
Mathias Anselmann, Markus Bause, Gunar Matthies +1
We provide an error analysis for the solution of the nonstationary Stokes problem by a variational method in space and time. We use finite elements of higher order for the approxim…

Optimal order FEM for dynamic poroelasticity: Error analysis for equal order elements
Markus Bause, Mathias Anselmann
The numerical approximation of dynamic poroelasticity, modeling flow in deformable porous media, by a family of continuous space-time finite element methods is investigated. Equal…
