PyFMI 1.3

A package for working with dynamic models compliant with the Functional Mock-Up Interface standard.

Latest Version: 2.4

PyFMI is a package for loading and interacting with Functional Mock-Up Units (FMUs), which are compiled dynamic models compliant with the Functional Mock-Up Interface (FMI), see for more information. PyFMI is based on FMI Library, see .

FMI is a standard that enables tool independent exchange of dynamic models on binary format. Several industrial simulation platforms supports export of FMUs, including, Dymola,, OpenModelica and SimulationX, see for a complete list. PyFMI offers a Python interface for interacting with FMUs and enables for example loading of FMU models, setting of model parameters and evaluation of model equations.

PyFMI is available as a stand-alone package or as part of the distribution. Using PyFMI together with the Python simulation package Assimulo adds industrial grade simulation capabilities of FMUs to Python.
