About Parameters

A parameter is a quantity within an FMU component's abstraction that remains constant during the experiment.

Your FMU components might include parameters that were defined in the systems modeling language or authoring app. These parameters must be assigned values to allow computation of the FMU during experiment execution. A parameter is similar to a variable declaration in a programming language; for example, x or temperature. In your experiment you could then set x=3 or temperature=299.

As another example, an FMU might include a parameter freq representing the rotation frequency of a computer cooling fan. In your experiment you could then set this parameter equal to 2400 Hz (cycles per second).

Parameters are supported only for FMUs, not for 3D physics simulations.
