Flow123d
Description
Flow123d is a simulator of underground water flow, solute and heat transport in fractured porous media. Novelty of this software is support of computations on complex meshes consisting of simplicial elements of different dimensions. Therefore, we can combine continuum models and discrete fracture network models.
Current version includes mixed-hybrid solver for steady and unsteady Darcy flow, finite volume model and discontinuous Galerkin model for solute transport of several substances and heat transfer model. Using operator splitting, we support models for various local processes including dual porosity, sorption, decays and simple reactions.
Computations can be run in parallel using MPI with scalability up to hundreds of processors. The input interface based on JSON file format allows specification of general space-time dependent data for any physical parameter that does not compromise performance. Program supports output into GMSH and VTK formats.

Usage
Upcoming modulesystem change alert!
Due to large number of applications and their versions it is not practical to keep them explicitly listed at our wiki pages. Therefore an upgrade of modulefiles is underway. A feature of this upgrade will be the existence of default module for every application. This default choice does not need version number and it will load some (usually latest) version.
You can test the new version now by adding a line
source /cvmfs/software.metacentrum.cz/modulefiles/5.1.0/loadmodules
to your script before loading a module. Then, you can list all versions of flow123d and load default version of flow123d as
module avail flow123d/ # list available modules module load flow123d # load (default) module
If you wish to keep up to the current system, it is still possible. Simply list all modules by
module avail flow123d
and choose explicit version you want to use.
