Webb11 feb. 2024 · Division in the Modelica code are safe, other divisions are not considered safe. Thus der (x)/der (y)=5 indicates that division by der (y) is safe (even though it clearly isn't), whereas solving that equation technically involves dividing by 1/der (y) which isn't deemed safe (as it didn't occur in the Modelica code).
