A quasi-optimal space-time FEM with local mesh refinements for parabolic problems
A talk in the BI.discrete series by
Johannes Storn from Universität Leipzig
| Abstract: |
We present a space-time finite element method for the heat equation that computes quasi-optimal approximations with respect to natural norms while incorporating local mesh refinements in space-time.
The discretized problem is solved with a conjugate gradient method with optimal preconditioner for problems with initial conditions $u_0\in H^1_0(\Omega)$ and almost optimal preconditioner when $u_0\in L^2(\Omega)$.
