gem example (multi-element chemical equilibrium calculation)

Here is an example of gem calculating the equilibrium of the O-H-As system, including gas, condensed, aqueous phases (Omega version).
Operation details Advanced Usage Gibbs energy minimizing algorithm in gem:Solving the Chemical Equilibrium Problem Using the Gradient Projection Method

1. Setting calculation condition (Cases sheet): You can set the partial pressure of gas, activity of aqueous species, as well as the initial number of moles.

2. Results as number of mols (Results sheet)

3. Results as activities (Activities sheet)

Above 3 sheets and Monitor sheet, which diplays status of the calculation, can be copied to excel file by copy4sheets menu --->Excel display
