When excecuting:

Plotting the initial state

First, an instance of the model of the kite control unit (KCU) is created which is needed by the Kite Power System model KPS3. Then we create a kps instance, passing the kcu model as parameter. We need to declare the type of these variables to achieve a decent performance.

using SymbolicAWEModels
kcu::KCU = KCU(se())
kps::KPS3 = KPS3(kcu)

I get:

julia> kcu::KCU = KCU(se())
ERROR: UndefVarError: `KCU` not defined in `Main`
