Description

DuMux (https://dumux.org/) is a general simulation framework (written in
C++) with a focus on finite volume discretization methods, model coupling
for multi-physics applications, and flow and transport applications in porous
media. Its core applications are single- and multiphase-flow applications in
porous media on the Darcy scale, embedded network and fracture models, and
free-flow porous media flow interaction. However, it can also be used as a
general-purpose finite volume / control-volume finite element solver for partial
differential equations. Pre-implemented models make it a versatile tool for many
porous media applications.
In this poster contribution, we give a brief overview of the main features and
application areas. Moreover, we present updates in recent years (including the
upcoming release of DuMux version 3.11, Spring 2026) and how the capabilities
have improved since the initial appearance of DuMux 3.0 [1]. Novelties include
additional (pore-)network modeling capabilities, 2D shallow water equations
(e.g. for river modeling), new control-volume finite element schemes, meth-
ods for free-flow porous media coupling, fractured porous media, multithreaded
assembly, and new tutorials and educational material.
Given the theme of the conference, we put a special emphasis on “Green
housing” applications and models in DuMux. DuMux is based on the DUNE
framework from which it uses the versatile grid interface, vector and matrix
types, geometry and local basis functions, and linear solvers. DuMux then pro-
vides finite volume discretizations (Tpfa, Mpfa, Staggered) and control-volume
finite element discretization schemes (P1, CR/RT, MINI); a flexible system
matrix assembler and approximation of the Jacobian matrix by numeric dif-
ferentiation; a customizable Newton method implementation, and many pre-
implemented models (Darcy-scale porous media flow, Navier-Stokes, Geome-
chanics, Pore network models, Shallow water equations) and constitutive mod-
els. DuMux features a multi-domain framework for model coupling suited to
couple subproblems with different discretizations/domains/physics/dimensions/. . .
and create monolithic solvers.

tions from over 80 developers. The poster contribution will mention the poster
authors and acknowledge an updated list of developers actively contributing to
DuMux since the release of version 3.0.
