问题
I am simulating a heat pump water heating system in Modelica. I have attached the picture of my model. However, when I run the model I get the error "Medium is partial, name lookup is not allowed in partial classes". Can you please let me know:
- How should I specify the water in tank, heat pump condenser and pipe?
- How should I specify air in heat pump evaporator?
And in general, I did not find any example of modeling thermal systems in Openmodelica, can you suggest a source?
Thanks
