Coupling of COMSOL and PHREEQC for the Simulation of Environmental Flow and Transport Processes with Geochemical Reactions

COMSOL_PHREEQC is a software tool that couples the generic finite element solver COMSOL Multiphysics® with the geochemical modeling framework PHREEQC to simulate a wide variety of environmental flow and transport processes (COMSOL) together with comprehensive geochemical reactions (PHREEQC).

    Dr. Wissmeier can be contacted at The tool is realized through MATLAB and COMSOL’s LiveLink® together with the COM version of PHREEQC, called IPhreeqcCOM. Software requirements: • MATLAB® (tested version: 8.0; release 2012b) o With the optional Parallel Processing Toolbox, geochemical reaction calculations can be distributed among multiple processors. • COMSOL with MATLAB LiveLink (tested version 4.3a) • COM version of IPhreeqc (tested version 2.18.5570; available free of charge at For the user-friendly creation of coupled models, the common graphical interfaces of COMSOL and PHREEQC are employed.
