I have tried modelling siderite-magnesite solid solutions using the community version of GWB. I decided to check the properties of various carbonates used in model calculations, including calculation of molar volumes for pure carbonate phases from unit cell parameters. I obtained generally good agreement with GWB properties listed for calcite, magnesite and rhodochrosite, but found a large difference between the GWB value (28.630 cm3/mol) and a value calculated from unit cell data (29.376 cm3/mol) for siderite. Also, I don't appear to be able to access the continuous SS modelling option in the community version. Would anyone care to comment?

As a novice user of React I'm trying out a few test examples using formats given in the GBRM book. Currently I'm working through the "Lyons Sandstone" problem; but typing and saving my own script files. The problem I'm having is that when I try to use the "read" command to react my meteoric fluid (that I've already created and saved) with the example brine I get the error message "Can't find file". I figure that the file is probably not in the right directory (although I've saved the metaoric fluid script file into the Script folder within the GWB folder). Can anyone offer a simple solution that would enable the program to find my meteoric fluid file and proceed with the simulation?
