Simantics tutorial : Population model
This model is in the True package
Population model is a model from Simantics Tutorial : Basic System Dynamics Modelling

This model has been replicated in software TRUE.

Simantics software operation seems identical to Vensim and IThink software:
  • Valves that update stocks, are all open at the same time before starting the calculation of the next time unit.

    To simulate this principle in software TRUE, the parameter Rate of the action of a flow that links two stocks is enable, the chronologies of the flows are not automatic in the software TRUE, the are manualy initialized according the causalities.
