  1. Hello, Is there any indication of which database was drawn from when looking at an output file? Thanks! Michael
  2. Thank you Brian. Log K's are unavailable, but definitely good to know adding one will help with balancing. Best, Michael
  3. Also, You asked if I could load it into other programs. The answer is no- not within GSS, where I've worked extensively with SpecE8 in the past. Thank you.
  4. Brian, Thanks for the quick reply! Release 10.0.2 (Build 6257) 32-bit This forum says 'You aren't permitted to upload this kind of file'. It's a .tdat file... Please advise. Thanks, Michael
  5. Hi Brian, Thanks for your reply. However, after reading it and the suggested post about loading the proper dataset, it still is not showing up. Here is what I just did: 1) Closed all instances/programs of GWB. 2) Opened the thermo database editor and confirmed a- my added basaltic glass was there (yes), and b- that the mineral count says 635 not 634 of the previous iteration (yes) 3) Closed the thermo editor 4) Opened RXN 5) File >>open>>thermo data... --> chose the one I just confirmed to be correct in step#2, but when I do, the temporary dialogue box says 6
  6. Hello, I'm trying to add to the thermo.dat database a basaltic glass so that I might balance its dissolution with CO2 consumption. In the database editor everything seems fine up until I try to 'save.' Save-as works fine, but just using 'save' doesn't proceed- I get some sort of permissions error. Fine- I can save-as once I'm certain of my changes with a new name. It won't even let me save-as then replace an existing name, btw. When in RXN, I chose the new and improved database with my basaltic glass included. (Which I've just checked by opening only the database editor) But the t
  7. Hello, We are interested in modeling the precipitation (SI values) of birnessite from Mn^2+ that is released to solution by dissolution of primary Mn(II)-bearing silicates. In our system, this Mn(II) reacts with dissolved O2 to form birnessite. However, when we model birnessite precipitation, aqueous species include manganate(VI). The birnessite precipitation reaction in thermo.dat is the disproportionation reaction: Mn8O19H10 + 4H+ = 5Mn^2+ + 3MnO4^2- + 7H2O Therefore, we are wondering if there is another way to model the precipitation of birnessite from Mn2+ solutions that
  8. Brian, Thanks for the reply. The new interface looks great, and I look forward to using it. I added the old fashioned way a couple months back... As a follow up, I'd like to ask two things: When adding mineral phases to the database, is it critical to then adjust the mineral phase total in the header section for each addition? e.g. 624 to start, 625 for one addition. Is this total something GWB/SpecE8 ignores during operations? On Slide 10 of the tutorial, a box denotes that info located in this section is optional. Is it pointing only to the mineral "type" entry? Or are mola
  9. Hello, I'm double checking my database alterations, and I seem to recall a video on Youtube that highlighted the steps really well. Is that video still available? Thanks, Michael
