Is there a way to list of parameters of FMU (or of submodel in FMU) using the python libraries FMPy or pyFMI?

Question

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 us

Answer 1

With fmpy you can loop over the modelVariables in the model description as follows:

from fmpy import read_model_description
from fmpy.util import download_test_file

fmu_filename = 'CoupledClutches.fmu'

download_test_file('2.0', 'CoSimulation', 'MapleSim', '2016.2', 'CoupledClutches', fmu_filename)

model_description = read_model_description(fmu_filename)

parameters = [v for v in model_description.modelVariables if v.causality == 'parameter']
