pyfmi

问题 I have a FMU of a model and the use case is to change parameter values of the FMU to see the impact on the results. Is there a way to list top level parameters of the FMU using either FMPy or pyFMI if I dont' have access to the Modelica model? One of the process I have been following is to open the FMU using FMPy.gui and go through the list of parameters and then use them in the script but I would like to know if there an easier way of doing it so that I can list then in the Jupyter notebook

问题 My goal is to be able to run FMUs produced by OpenModelica in Ubuntu 18.04 and then run these with PyFMI in Python 3 environment. I follow the outline for PyFMI installation here https://jmodelica.org/pyfmi/installation.html. So far I have using Conda managed to install Python3, Numpy, Scipy, lxml and some other packages and made it work with some of my Python examples. But I would appreciate some detailed advice how to Install FMI Library - and I do not get how to setup the flag fmil-home

问题 Following this question, I'm trying to compile and simulate a Modelica model with JModelica. The model is: package friction1D function coulombFriction input Real relVel; input Real shearForce; input Real normalForce; input Real statfricco; input Real kinfricco; input Real inertia; input Real relAcc; output Real fricForce; algorithm if (relVel == 0) and (abs(shearForce - inertia * relAcc) < statfricco * normalForce) then fricForce := shearForce - inertia * relAcc; else fricForce := kinfricco *

问题 Following this question, I'm trying to compare the results of the simulation between JModelica and OpenModelica. The Modelica file is identical to the above-mentioned post and the JModelica wrapper is the corrected version: #%% from pymodelica import compile_fmu from pyfmi import load_fmu import matplotlib.pylab as plt #%% model_name = 'friction1D.fricexample_1' mofile = 'friction1D.mo' #%% fmu_name = compile_fmu(model_name, mofile) sim = load_fmu(fmu_name) #%% opts = sim.simulate_options()
