ABSTRACT: This talk is about semi-explicit time-stepping schemes for coupled elliptic-parabolic problems as they arise, for instance, in the context of poroelasticity. If the coupling between the equations is rather weak, such schemes may be applied. Their main advantage is that they decouple the equations and therefore allow for faster computations. Theoretical convergence results are presented that rely on a close connection of the semi-explicit schemes to partial differential equations that include delay terms. Numerical experiments confirm the theoretical findings.
