Oh I see what you mean.
Yes, this is an incomplete model, in the sense that without defining its connections it’s not simultatable. @mtkbuild
is meant to be building final models, and so it’s running that check and mentioning that ac_test
is not runnable. You don’t end up using ac_test
in your ODEProblem though so it doesn’t end up mattering. It is okay to have partial models which are then connected to build a complete model, in fact every resistor, capacitor, etc. are components which do not make sense in isolation and require being connected to be completed, so it’s not odd or rare to have this kind of component.
