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.
