Is voltage the input and current the output, or the other way around? You commit, you write the function, and the function only ever runs that one way. Write the same resistor in Dyad and you do not pick a direction at all. component Resistor parameter R::Resistance relations v = i * R end That is the whole model: a parameter and one equation.
