Model Based Development and Data Processing Kit​

Introduction to the Use Case​

The Behaviour Twin MDP (Model based development and Data Processing) Application was developed as proof-of-concept within the framework of the Catena-X initiative, to demonstrate collaborative utilization of behavioural digital twins in the automotive industry. This innovative application is poised to define the workflow and the tool chain for the model-based system development and data processing, leveraging Catena-X technology and collaborative principles. The mission of the Behaviour Twin MDP Application is to provide a comprehensive framework for the selection, integration, and utilization of behavioural digital twins. Through adherence to Catena-X standards and principles, we strive to ensure secure data exchange, interoperability, and compatibility, laying the foundation for seamless collaboration and efficiency in innovation.

The objective is to enhance model-based design and data processing using models coming from component suppliers (for example: the OEM gets the models of the gear box, the brakes and the battery from the respective Tier1s), by facilitating model exchange between Tier1s and OEM or between Tier2s and Tier1. This is done using the industry standard FMU (Catena-X standard CX - 0102 Functional Mock-Up) and performing the exchange over EDC. The MDP KIT defines the functionality of the software applications needed for the MDP use cases, that is to combine the models into a simulation architecture and perform parametric studies, but also to do field data processing based on evaluation models of the component suppliers.

General Information Display: Behaviour Twin MDP Application​

The General Information Display of the Behaviour Twin MDP (Model and Data Processing) Application offers users a user-friendly interface to visualize essential information about behavioural digital twins and their components. Whether users are analyzing the behaviour of a component within a vehicle or maintaining a system, this feature provides easy access to valuable insights.

A technical expert from the OEM has the task to build a design of a new car. The simulation expert will collect the necessary models from the Tier1 and combine them in a vehicle model to evaluate different designs. The models are exchanged between Catena-X partners using EDC and using the FMU format (black box model).

Overview Application

Once the models are available the workflow proceeds in three steps: Verify that the FMUs are valid (conform to the industry standard). Get information about the model inputs/outputs to make sure that you got the right models. Get the model in Simcenter System Architect over Teamcenter Share (which is being connected to EDC). The models are composed in a larger model (called Architecture) Get the architecture in Simcenter HEEDs and run parametric studies and compare results to evaluate the design.

FMU Checker​

FMU checker: to check the model and gain insights (for example what are the inputs and outputs).

MDP Development Video​

This video demonstrates the necessary software application functionality for implementing the MDP Use Cases:

  • A guidance app, such as the MDP App shown in the video, should be provided to assist users in collaborative model-based development or model-based data processing workflows.
  • In the video the two use cases are showcased with software applications from the Siemens Simcenter portfolio. Namely with Simcenter System Architect for the Model Integration step, Simcenter HEEDS for the Model Execution step and in the 2nd use case with Simcenter Testlab Neo for the Data Processing step. These Apps have been chosen for illustrative purposes.
