Section 1.2 Basic Examples
The fundamental building block for all Insights is the integrator:
In this example one can modify the flow rate function and initial condition of the stock to obtain the antiderivaive of the given flow function with the given initial condition.
A key fact is that we can use any stock that is up- or downstream of a given flow in the formula for its flow rate. Moreover, we may link parameters, which may be manipulated with sliders, and run simulations numerically. For instance, we have the standard Malthusian growth model given below.
