The Open Model section of the Dynochem ribbon allows you to open your model in the Simulator, Fitting or Optimization windows:

Simply click the indicated icons to open your model in the desired environment.  This will initiate 'parsing' of the model to check for any errors that would prevent successful conversion of your Excel sheets into a mathematical model that can be integrated in these environments.

Parsing:

• If you already have the model open in one of these environments, you will be asked whether you wish to overwrite it with the new model you are parsing.  This prompt will appear only if both models came from Excel workbooks of the same name.
• If your model parses without errors, you will be presented with a new screen outside Excel where you can continue to work on your model (e.g. simulate, fit parameters, optimize operating conditions).

Running:

• For a model that is new to you (or one which you have recently edited), we recommend that you visit Simulator first, to ensure that the model is consistent with what you expect and that it runs to completion. 
  • If you change parameter values in Simulator and wish to use these changes immediately in Fitting or Optimization, use the update button to commit the changes to memory 
  • If the model is in good working order, use the 'model icon', right-click menu options or keyboard shortcuts to move into Fitting or Optimization (see below).
• If you are very confident that your model is working well, you can open it directly in Fitting or Optimization from the Dynochem ribbon.

Click to obtain more detailed information about using Simulator, Fitting and Optimization.

If you intend to run your model using any of the items in the Run Model section of the Dynochem ribbon, we recommend that you first check that your model is running well by opening it in Simulator.

As you move between the Simulator, Fitting and Optimization screens with your model, you may wish to take recent changes with you into the next environment.  For example, fitted parameters obtained using the Fitting window can be updated before running in Simulator or Optimization.  Or a new scenario created in Optimization can be added to the model before examining the results in detail using Simulator. 

Use  in any of the windows to commit changes to memory and then click the model icon to open the model (including these changes) in the next environment,

When you are working in these screens and want to commit changes to your Excel model, use .  This will commit cumulative changes made since parsing the model to the Excel file. 

To save these changes to disk permanently, use File>Save in Excel.

New in Dynochem 5, you will find many useful shortcuts available in Simulator, Fitting and Optimization.
