FMI Toolbox: Use of Modelica-based models as FMU in DYNA4

In the simulation framework DYNA4 models and model parts can explicitly be managed and complied to virtual vehicles. Simulink thereby works as the integration platform. DYNA4 enables the integration and combination of models from different simulations tools, that support the model export in accordance with the FMI standard (Functional Mock-Up Interface). Thus model parts such as from Dymola, SimulationX or Amesim can be combined with Simulink models. With the „FMI Toolbox for Matlab“ physical models are seamlessly integrated in DYNA4, so that the integrated FMU model parts can be operated and managed just as the Simulink model parts. Regardless of their origin, the entire functionality of the DYNA4 framework is available for all model parts.

Application examples

  • Variant tests in DYNA4 as vehicle dynamics integration environment
    Numerous vehicle variants and soft-ECUs based on Simulink can be combined, parameterized and administrated, e.g with physical steering models.
  • Consumption calculations with DYNA4 for powertrain design
    Automated calculations of driving performance and fuel consumption with integration and administration of physical powertrain models, e.g. from Dymola.


  • Wide range of benefits within one user interface
    Parameterization, automation of simulations and traceable results are managed in one surface. You can compile all available models for your tests easily on the DYNA4 user interface to the virtual vehicle.
  • Inter-divisional use of a heterogeneous model landscape
    Through a centralized, secure storage structure and versioning models or model parts can be exchanged inter-divisionally, even from different simulation surfaces.
  • Model use with modularity by defined interfaces
    In order to combine the models in a modular way, DYNA4 contains a model architecture with well-defined interfaces.  You thereby receive a convention for overall model exchange - all available models can be used togehter as a toolkit.
