Hi,
I have a problem with the varible flow during the programing in Modelica, the software always takes me this varible flow = 0 (voulumique or mass flow);
Please could you give me a small example so that I can analyze things.
In advance thank you very much.

class Boucle.Flow
  parameter Real q(quantity = "VolumeFlowRate", unit = "m3/s", start = 10.0);
  Real T(quantity = "ThermodynamicTemperature", unit = "K", displayUnit = "degC", min = 0.0);
  Real p(quantity = "Pressure", unit = "Pa", displayUnit = "bar");
equation
  q = 0.0;
end Boucle.Flow;
