Hi
Is there anyone who can me help me please. I am doing LNG plant optimization. To perform the optimization I first did the simulation on Hysys and interface HYSYS with Matlab. The model is still now in steady-state condition. When I am using the compressor outlet pressure as the decision variables, The simulation is working and it can minimize the energy consumption.
But, when I am using the refrigerant mass flow rate or outlet pressure of throttle valves as decision variables, the simulation get's unconverged and the simulation stopped.
In addition to this, when I am using refrigerant mass fraction as decision variables and run the optimization it shows the following error "Invoke Error, Dispatch Exception: No such interface supported"
If I the convert the simulation into dynamic mode, the problem will be solved ?
whenever, i am trying to convert the model into dynamic it's showing that notification in this picture.

Thanks a lot for your sharing.
Sorry, I am not working on mixed refrigerant, but on air, sorry that I cannot help with your problem now, but hope we can communicate with and help each other more later.
Thanks.
Best regards
