It provides A simulation is performed by using the simulate method. The PyFMI on the chria channel is not being maintained. The one on conda-forge seems to be the best place to get the binary package. The _fmu-export-actuator.idf simulation is in fact three days long, and differences are only visible on the third day! Initialising yShade is not enough, you must pass it in to the input parameter of simulate(). Simulating FMUs with the CyDER utility¶.

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 .

In this article, the Python package PyFMI is introduced. PyFMI supports loading and execution of models compatible with the FMI standard. Such mod-els are called Functional Mock-up Units (FMUs). PyFMI is based on the open source package FMI Library [2]. It is designed to provide a high-level, easy to use, interface for working with FMUs.

PyFMI is commonly used with Assimulo [11]. Assimulo is a package that provides solvers for solving dynamical systems, such as those represented by FMUs. The packages complement each other as Assimulo provides the solvers and PyFMI provides the problems. PyFMI o ers an open platform for working with FMUs and the algorithms
""" This file contains code for mapping our JMI Models to the Problem specifications required by Assimulo.

I'm changing the initial 2 parameter values (over the range of possible values) with pyFMI and simulate the model response I can see that my response is affected only by 1 variable change and not by the other but if I simulate the model only with the second variable (that is not changing in inital simulations) I can clearly see the PyFMI is also demonstrated on a number of problems that highlights its viability for solving industrial grade simulation problems with FMUs.}, author = {Andersson, Christian and Åkesson, Johan and Führer, Claus}, institution = {Centre for Mathematical Sciences, Lund University}, issn = {1403-9338}, language = {eng}, number = {LUTFNA-5008-2016}, series = {Technical Report in Mathematical ture provided by PyFMI since it provides an interface to the FMU model that allows to set state variables, parameter and running simulations. 2.2 The Unscented Kalman Filter The Unscented Kalman Filter is a model based-techniques that recursively estimates the states (and with some modications also parameters) of a nonlin- Andersson, C, Åkesson, J & Führer, C 2016, PyFMI: A Python Package for Simulation of Coupled Dynamic Models with the Functional Mock-up Interface.Technical Report in Mathematical Sciences, no. 2, vol. 2016, vol.
