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. Laurin Wissmeier
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.
