December 8th – Luca Formaggia: Hybrid dimensional Darcy flow in fractured porous media, some recent results on mimetic discretization

Luca Formaggia: Thursday 8 December at 3pm, A415 Inria Paris.

Fractures can alter greatly the characteristics of porous media. Their diverse scale distribution makes it often impossible to resort to averaging or homogenisation techniques to account for their presence. Thus, different models have been devised to account for the presence of fractures in porous media explicitly. We here present the general problem, together with a recent result of well-posedness for an hybrid dimensional mixed formulation of Darcy flow in fractured porous media, and an analysis of a mimetic finite difference scheme adopted for its numerical solution.
