Methods and Tools for Co-Simulation of Dynamic Systems

A Software Framework for - AVHANDLINGAR.SE

Introduction¶. This is the source tree or distribution for the otfmi package for simulating functional mockup units (FMUs) from OpenTURNS. The functional mock-up interface (FMI) standard specifies a format for multipurpose, easy to build and reusable data interfaces to numerical models. The thesis is based on the Python package PyFMI, a high-level package developed by Modelon AB for working with models compliant with the FMI standard. The algorithms were tested on test cases consisting of several synthetic examples as well as in a simulation of a real industrial physical model. 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 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 An example network consisting out of two inverters, three filters and an inductive load. You can either use one of the provided FMUs (Windows and Linux, 64-bit, both included in the grid.network.fmu) or create your own by running: I ran into another issue here with the example Tom shared originally.

Modelica model used to export co-simulation FMU from Dymola (using CVode) Python code as py file 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 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. Simulating EnergyPlus FMU with JModelica and PyFMI. The main difficulty I had was making the number of communication points (ncp) match up given the final_time. I ran this in JupyterLab (.ipynb) but it should work in ipython or in a .py script. The output chart should look something like this: I'm trying to simulate the examples included in the pyFMI (Bouncing_ball example) tutorial just to be sure that everything is working fine.

For instance it can be a change of the continuous states in the model as the Basic example with pyfmi. I am trying to run a dummy test to call EnergyPlus in Python as a FMU.

PyFMI is available as a stand-alone package or as part of the JModelica.org distribution. Where the flag “–fmil-home” should point to where FMI Library has been installed. I am trying to simulate multiple Modelica FMUs in parallel using python/pyfmi and multiprocessing.
