Coupled Fracture Network – Porous Rock Matrix Flow on Non-Matching Grids with XFEM

Dr. Bernd Flemisch und Dipl.-Ing. Nicolas Schwenck (University Stuttgart)


Fractured porous-media systems are simulated, where the characteristic

flow behavior depends on both the fractures and the matrix. A structured

rock-matrix grid is coupled with an independent, arbitrarily orientated

fracture-network grid of codimension one that leads to discontinuous

solutions across the fractures which are handled by an XFEM approach.

Discontinuities also occur at fracture crossings. A consistency

condition which can handle arbitrary crossings is presented as well as

consistent boundary conditions for fractured boundaries.
