Hallo

The example models will successfully simulate when they are given with proper Initial conditions (start values and other values you give to models in diagram view). Since the example models in modelica library is uneditable it is not possible to Change any Initial values in these models and hence Simulation fails. So i suggest you to make your own model and copy to it the entire code from desired example model in library. Now give reasonable Initial conditions to the models. This worked for me.

Best regards

Joel,

Thanks for the reply. I did as you suggested, but running into issues with the model being singular or overdefined. Would you happen to have any recommended initial values that would not cause this? As well as which components require initial conditions/parameters to run successfully?

I apologize, I am very new to OpenModelica. Thanks for any help!

Best,
Jeff

Hallo Jeff

The error you mentioned can be because of defining initial values for more variables than needed or incorrect values in the model. More Information required to tell about it correctly. Debugging and using flags while compiling are usual options to solve these.

Best wishes
