Tom Meuzelaar Posted May 13, 2008 Share Posted May 13, 2008 [admin notice: the below is from the former GWB users group email distribution list. This message was originally posted 9/29/2003] Posted by: Craig Bethke We have converted the thermodynamic databases from the following software packages to the GWB format: • Visual Minteq release 2.20 • PhreeqC release 2.8 • Wateq4F These databases will be included in the upcoming release 5.0 of the GWB. All databases can be downloaded here. Important note: there are two versions of each of the databases. The first version, marked "_gwb4", is for use with current GWB releases (4.0.x). In this case, the GWB programs will use the default activity model (the debye-Huckel B-dot equations) to calculate activity coefficients. As such, the speciations predicted will differ slightly from those reported by the original application (Minteq, etc.). The second version of each is intended for use with future releases of the GWB (5.0 and later). The GWB applications, used with these versions, will employ the same methods for calculating activity coefficients as the original applications, and so the results given will be more precisely comparable.
