Coupling Model Exchange FMUs for Aggregated Simulation

Screenshot of the dependency graph visualization

I recognized that initializing the individual EnergyPlus models takes quite some time. Therefore, I hope to find a way to initialize the models in parallel. If it matters, I am on Ubuntu 16.10 and use Python 3.6. Here is what I want to get done in serial: I set environ FMIL_HOME and still cant install pyFMI.

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/. Contribute to modelon/PyFMI development by creating an account on GitHub. 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. PyFMI supports loading and execution of models compliant with the FMI standard, called Functional Mock-up Units (FMUs). It includes a master algorithm for simulation of coupled FMUs together with connections to both Assimulo, for simulation of single FMUs, and to SciPy, for performing parameter estimation.

The result is returned and stored in res.

For a more detailed description on how to use PyFMI, see the user’s documentation in JModelica.org. I am trying to simulate multiple Modelica FMUs in parallel using python/pyfmi and multiprocessing. However I am not able to return any pyfmi FMI objects from the subprocesses once the FMUs are initialized.

The simulation is in real time with inputs and outputs that are changed each cycle. To do this have I taken a lott of inspiration from the fmi example bouncing_ball_native that comes with the pyfmi package.

My EnergyPlus has 60 seconds as the timestep size. It looks like it can not go through.

The extension enables coupling of FMUs and models written directly in Python to a so- I set environ FMIL_HOME and still cant install pyFMI. Is it possible to set pyFMI for windows 10 64bit with python 3.7+?

I am trying to simulate multiple Modelica FMUs in parallel using python/pyfmi and multiprocessing. However I am not able to return any pyfmi FMI objects from the subprocesses once the FMUs are initialized. It seems that pyfmi FMI objects (e.g. pyfmi.fmi.FMUModelCS2 or pyfmi.fmi.FMUState2) are not pickable. PyFMI supports loading and execution of models compliant with the FMI stan- dard, called Functional Mock-up Units (FMUs). It includes a master algorithm for simulation of coupled FMUs together with connections to both Assimulo, for simulation of single FMUs, and to SciPy, for performing parameter estima- tion. Module for simulation algorithms to be used together with pyfmi.fmi.FMUModel.simulate.
