mosaik-fmi 1.1.0.post0

Installation

• mosaik-fmi is based on the FMI++ library, which can be found at https://fmipp.sourceforge.io/

• The FMI++ python interface is used, which can be found at https://github.com/AIT-IES/py-fmipp. See this page also for details about installation and requirements of the python interface.

Test

The FMUs for the test is based on https://github.com/modelica/Reference-FMUs.

How to Use

Specify simulator configurations within your scenario script:

sim_config = {
    'FMI': {
        'python': 'mosaik_fmi.mosaik_fmi:FmuAdapter',
    },
    ...
}

Initialize the FMU Simulator:

fmu_sim = world.start('FMI',
                    integrator='integratorCK',
                    work_dir='path/to/the/fmu/directory',
                    fmu_name='FMU_name',
                    fmi_version='2',
                    fmi_type='cs',
                    logging_on=False,
                    instance_name='FMU_name',
                    step_size=60*60)

Instantiate FMU model entity:

fmu_entity = fmu_sim.FMU_name.create(1,
                             input_1=1.0,          #  FMU input variable
                             input_2=2.0,          #  All variables are listed in modelDescription.xml
                             ...
                             )

Connect FMU output to another simulator’s input:

world.connect(fmu_entity[0], other_simulator,'fmu_output_1', 'simulator_input_1')

Selecting integrator

Refer to https://fmipp.readthedocs.io/projects/py-fmipp/en/latest/getting-started/model-exchange.html#classes-fmumodelexchangev1-and-fmumodelexchangev2 for choosing different integration algorithms
