Hi, I'm an energy engineer and i tried to use DWSIM for a few weeks.

It's an amazing software and for my simple tasks (not advanced chemistry processes but only thermodynamic and combustion) i think that it's wonderful.

In DWSIM a Joule-Bryton cycle is easy to simulate because there is a constant-pressure heat trasfer (or constant-pressure combustion), but i don't know if it's possible to simulate a constant-volume heat transfer (isocoric) or better a combustion like a otto cycle. Can you help me?

Thanks a lot.

Have a nice day.
