This is less flexible than the previous master, as it can miss events if time-steps are too large. PyFMI is a package for loading and interacting with Functional Mock-Up Units (FMUs) both for Model Exchange and Co-Simulation, which are compiled dynamic models compliant with the Functional Mock-Up Interface (FMI) - modelon-community/PyFMI Git mirror of https://svn.jmodelica.org/PyFMI/.

Simulation of FMI models in Python Dear all, I tried the FMI export from OpenModelica 1.8.1 beta with the Python packages PyFMI and Assimulo to test scripting of simulations of OpenModelica models in Python.

I wrapped one energyplus reference building into FMU and try to simulate the Energyplus-fmu using Pyfmi.

To do this have I taken a lott of inspiration from the fmi example bouncing_ball_native that comes with the pyfmi package.

And I try to run it from Python using pyfmi. Co-Simulation with PyFMI¶ In this example, FMUs are exported as Co-Simulation and therefore they come with an embedded solver. The PyFMI master algorithm requests FMU to do steps with a given step size (0.5 seconds here). This is less flexible than the previous master, as it can miss events if time-steps are too large.
