3) AQUEOUS SPECIATION, SOLUBILITY, AND CHEMICAL MASS TRANSFER CODES
InsTRuctions for Running EQ Packages
(Intended for Mac only)
The packages below each contain three programs: EQ3, EQ6, and EQPT.
EQ3: This code is for completing aqueous speciation and solubility calculations.
EQ6: This code is for completing chemical mass transfer calculations.
EQPT: This code is used if any changes need to be made to the data file (DATA0). It writes DATA0 into data1, a form that can then be used by EQ3 and EQ6.
*Each package is confined to a certain temperature range and pressure and the DATA0 file contained within cannot be used in another package.
To begin any run you first need to open terminal.
For each run you need to set the folder that the terminal is drawing from. This is done by using the command cd followed by a space and dragging the folder into the terminal. If you begin by running EQ3, you should use the EQ3run folder. The command line should appear something like this:
Dimitri-Lab-iMac-3:~ david$ cd /Users/david/Desktop/New\ EQ\ Packages/EQs_at_300-650ºC/EQs\ at\ 300-650°C\ \&\ 5kb/EQ3run
Press enter to complete the command and continue. If you are successful the name of the folder should now appear in the command line similar to this:
Dimitri-Lab-iMac-3:EQ3run david$
To continue with an EQ3 run once the terminal is set to the EQ3run folder, open that folder. You should find the DATA0 and data1 files along with the EQ3 code. You will also need an input file in the folder. (An example can be found in the Ms+Ky+Qtx+Pg at 650 C or Ms+Sill+Qz+Ab at 650 C folders depending on the temperature range you are in.) Once these are in the folder you can complete the run by using the ./ command followed by the name of the code. When running EQ3 the command line should look like this:
Dimitri-Lab-iMac-3:EQ3run david$ ./eq3
Once you hit enter you'll know the run was successful if there is a line stating the hybrid newton-raphson iteration converged in x steps.
The next code to run is EQ6. (Again make sure that terminal is set to the correct folder, in this case EQ6run.) In the EQ6run folder there should be DATA0, data1, and EQ6. It also needs an input file, an example of which can be found in the Metapelite fluid + ultramafic rock folder. Finally, for EQ6, you will need the pickup file from the EQ3 run. This needs to be copied and pasted into the bottom of the input file beginning at the line that looks like this:
* pickup file written by eq3nr.3245R110
Once this is completed, you run the code using the same ./ command in terminal as before. You'll know it was successful if it says the reaction path has terminated normally.
EQPT only needs to be run if changes are made to DATA0, but if this is the case it is necessary for the DATA0 file and the EQPT code to be in the folder. Make sure the terminal is set to the EQPTrun folder and simply use the ./ command in the same way as the other codes. When you hit enter 3 questions should appear, type n and then enter to respond to each one. After this the code will process and a line should appear saying there was a normal exit.
