Pyfmi, OpenModelica FMU, and IPython (JSON involved) Trying to load an FMU compiled by omc (OpenModelicas compiler) provoke a nasty crash under IPython. Running import pyfmi pyfmi.load_fmu(path/to/fmu) makes IPython crash with

Is there a way to simulate a FMU in a C++ environment? FMU is widely used in a python environment thru FMI Library package pyFMI and compilation of modelica models can be done thru pyModelica. I wonder if there is a way to compile a modelica model

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. Is it possible to set pyFMI for windows 10 64bit with python 3.7+? I was able to create working environment with conda, but I am trying to work with pure python 3 interpreters.

PyFMI [5]. Some of the basic methods and classes provided by PyFMI have been extended to t our pur-poses. For example, we modied how FMUs are exe- These sigma-points are then propagated simulat-ing the nonlinear model (2) and the mean and covari-ance of the state variables are estimated from them.

PyFMI is an open source package (LGPL license) developed by Modelon. In this article, the Python package PyFMI is introduced.

from pyfmi import load_fmu m = load_fmu ('/path/to/spring_1d.fmu') res = m. simulate (0, 1) exit () So I close this one as this is related to pyfmi behavior. @markaren Unfortunately the segmentation fault arises when I'm using a FMU package with PythonFMU .

Using PyFMI together with the Python simulation package Assimulo adds industrial grade simulation capabilities of FMUs to Python. For a forum discussing usage and development of PyFMI, see http://www.jmodelica.org/forum. 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).

I want to use pyfmi to simulate individual time steps (with do_step) in EnergyPlus. 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:

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. from pyfmi import load_fmu opts = model.simulate_options() # set number of communication points dependent on final_time and .idf steps per hour.
