Presentation Transcript

  1. You can launch TEdit to view thermo datasets. From GWB apps, File → View → …\thermo.tdat From TEdit, File → Open → Thermo Data… → …\thermo.tdat From Windows explorer, double-click the file GWB’s default dataset.

  2. The Header section describes the dataset. Set the principal temperatures and activity coefficient terms in the Tables section All species are composed from the Elements. The Basis species are the building blocks. Redox couples, Aqueous species, Minerals, and Gases are formed by reaction between existing species and have an associated log K.

  3. Fill in the template to add the elements, species, etc. that you need in your thermo dataset. Right click → add Enter the new element’s name, symbol, and molecular weight, then click Apply.

  4. You can use TEdit to copy entries from one thermo dataset (the source) into another (the target). Open both datasets in TEditand select the entry you’d like to copy.

  5. You can rebalance reactions and automatically recalculate log Ks. Supply reaction and log Ks in terms of arbitrary set of species. Right click → add Automatically recast reaction in terms of Basis or Redox species. Final reaction as it will appear in thermo data → Apply

  6. You can exchange the position of Basis, Redox, and Aqueousspecies in a thermo dataset. Exchange the positions of basis species O2(aq) and redox species H2(aq). H2(aq) is the new redox pivot, and O2(aq) becomes a redox species. All affected reactions are automatically rebalanced.
