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 … Module for simulation algorithms to be used together with pyfmi.fmi.FMUModel.simulate. class pyfmi.fmi_algorithm_drivers.AssimuloFMIAlg (start_time, final_time, input, model, options) [source] ¶ Bases: pyfmi.common.algorithm_drivers.AlgorithmBase.

But with JModelica version 1.14 I get errors in the compiling process and my script fail. 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 .

Pyfmi simulate

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.

Modelica is a non-proprietary, object-oriented, equation based modeling language to conveniently model complex physical systems containing, e.g., mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents.
