Run custom functions🔗

A Custom Function is an integrated Python interface to Modelon Impact. With a Custom Function you define a script that does a computation or another operation on an FMU or a model, call it from the simulation browser and return the result to the result browser.

Impact supports Custom Function written in Python. If available, the icon appears next to the Steady -State button.


Custom functions are included in Libraries, so when the Library is utilized within a Project, all the Custom Functions contained in that Library can be selected. For the selected function, parameters can be set using input fields and toggles.

Modelon Impact comes with pre-installed Custom Functions, and Libraries or Projects can contain further "specific" Custom Functions.

  1. Project specific custom Functions

  1. Pre-installed "global" Custom Functions.
