Gibbs Energy Minimization
Software for Geochemical
Currently, GEM Software includes three code packages and a default
v.3 (GEMS3): the interactive code package for geochemical modeling
the standalone code for solving for geochemical equilibria (with
the generic parameter-fitting code coupled with the GEMS3K code
the default chemical thermodynamic database of GEM-Selektor package
GEM software is
distributed "as is" in its present state of development by the
Laboratory for Waste Management (LES) of the Paul Scherrer Institute
(PSI) with two
- to promote the GEM method and software into the academic
- to gather the users feedback, vital for making the software more
functional and reliable.
