smooth3

smooth3 is the system dynamics function that returns a third order exponential smooth of the input. It is frequently used to model information delays.

Example: 


smooth3 can be called in formulas of system dynamics variables.

smooth3 function has two notations:

input can be a flow variable, or a numeric expression of any complexity.

delayTime can be either a constant or a numeric expression (e.g. a function call, or a numeric parameter). It should return a positive number: smooth3 function with zero or negative delay time returns not a number. 

The simplified notation of the function. Is used when the initial value is zero.

Units: 

input -> units
delayTime -> time
initialValue -> units

smooth3() -> units

The output units are the same as the input ones.
