 I am a novice in Simulink and electric circuits
The attached simple model does not initialize.
I cannot figure out why.
Any hint is welcome.
Best regards

The model is missing a domain reference. Connect an Electrical Reference block to the active electrical circuit (for example to the negative terminal) and will work.
