Poroelasticity Benchmarking for FEM on Analytical Solutions

E. Holzbecher[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany

We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate.
