Component

The Component class provides a flexible interface for defining modular building blocks in an SSP model. It supports architectural modeling, allowing components to represent actual FMUs or “dummy fmus” with expected connectors and parameter values. This makes it possible to design and validate system architectures before all FMUs are available.

Key Features:

  • Flexible instantiation — create a component from an FMU or as a dummy placeholder.

  • Connector support — define inputs, outputs, and parameters with explicit causality and signal type.

  • Parameter management — assign values to parameters or inputs directly within the component.

  • SSV integration — link components to SSV files to define and manage parameter sets externally.

  • System integration — add the component to SSP models for hierarchical or flat system architectures.

from OMSimulator import CRef, Connector, Causality, SignalType, SSV
from OMSimulator.component import Component

# Create a dummy component
component = Component(CRef('add'), 'dummy.fmu')

# Add connectors
component.addConnector(Connector('input', Causality.input, SignalType.Real))
component.addConnector(Connector('output', Causality.output, SignalType.Real))
component.addConnector(Connector('parameter', Causality.parameter, SignalType.Real))

# Set parameter values
component.setValue('parameter', 1.0)
component.setValue('input', 2.0)

# Create an SSV file for parameter initialization
ssv = SSV()
ssv.setValue('parameter', 1.0)
ssv.setValue('input', 2.0)
ssv.export('dummy.ssv')

# Link SSV file to component
component.addSSVReference('dummy.ssv')

# List component details
component.list()
