GEM-Selektor v.3: Frequently Asked Questions 



How can I export/copy the data from GEMS3 module window page into an Excel worksheet?

After the calculation of single chemical equilibrium, GEMS3 asks to "Accept" or "Discard". What does the program do when I press "Accept"? when I click "Discard"?

How can I change air composition in Compos (PCO) list, e.g. to higher partial CO2 pressure?

After I have excluded an independent component (element) in a single thermodynamic system, how can I switch it on again?


Adding a new aqueous complex or a new phase to the thermodynamic database, in which data fields I have to enter something and what? (e.g. what can I do if I only have log K?)


After entering a new record in the thermodynamic database in one modeling project, how can I use this record in different projects? If I entered more records, how can I create an additional database file?


How can I upgrade GEM-Selektor to the most recently released version? 

How can I learn quickly to set up a system and calculate the equilibrium speciation using GEM-Selektor?
Download GEMS3 package and install it, as described on the distribution page. Start GEMS3,and execute "Help" "Tutorial" menu command to open the Help window with the Tutorial page. Do not close Help window and run the code in parallel with reading the Tutorial.
 
How can I report a bug?
Send us an e-mail to gems2.support@psi.ch. There, describe the problem briefly. Send us also (as an e-mail attachment) your (zipped) modeling project directory with comments indicating which database records have problems. In this case, your bug report will have a good chance to appear soon in the List of corrections.
