Coupling fluid flows with DuMuX

Many porous media applications involve multiphysics systems that can be separated by a sharp interface, for example coupling porous-media flow and free flow. The solver DuMuX (DUNE for Multi-{Phase, Component, Scale, Physics, …} [1]) is a C++-based open-source software that is used extensively for solving flow and transport processes in porous media.

This talk will focus on a new preCICE adapter that allows to couple DuMuX with DuMuX or other solvers aiming to be applicable to a wide variety of porous media applications. In the talk we discuss the development, the adapter’s current capabilities, and we give a short overview on how to use the adapter, especially in the context of coupling porous-media flow and free flow. We will conclude with the discussion of future plans and possible extensions of the adapter.
