Answers:

Please make sure that you are doing one of the following as explained in the tutorial:

1. If you have selected the Minimization Method as Calculate Reaction Extents, then you must add an equilibrium reaction with valid reaction parameters.

2. If you have selected the Minimization Method as Direct Gibbs Energy Minimization, then you must select the compounds in the Compounds tab and define the element matrix for the selected compounds in the Elements tab under Calculation Parameters. Also note that while you define the element matrix, please add the elements in the same sequence as shown in the tutorial.

If you still continue to face the issue, please mail your simulation file to contact-dwsim@fossee.in.

1. In the file sent, Input for the Elements count of Carbon Dioxide under Calculation Parameters is incorrect. It should be C-1, O-2. Click on Save Changes.
2. Increase the Outlet Temperature from 225 degree C to 226.85 degree C.
