I've created a project on Chemkin Pro for a single zone HCCI engine. I wanted to co-simulate between GT-Power and Chemkin. Can anyone provide me a tutorial that will help me create the user defined code to pass values from GT-Power to Chemkin at IVC and from Chemkin to GT-Power at EVO. The tutorial for co-sim provided with Chemkin was for a SI engine. I want to know how to co-sim for a my own project.
