Process modeling examples 

 

  • An effective way to start a new simulation is by modifying an example

  • AQSim and OLI have a large selection of example cases that will help you get started
     

  • Browse our examples below, and click on one to download the .esp file
     

  • Let us know if you would like an example you do not see here
    - chances are good we have it
