Why is System Simulation an essential asset in support of Model Based Systems Engineering?

In all business discussions we have with our customers and partners, we clearly observe that the race to innovation across industries leads to constantly redefining the way companies are working.  Let us put ourselves in the shoes of some of our industry users for a moment: do we have an idea about the complexity of designing autonomous vehicles (mechanical and controls) with so many parameters to be calibrated, so many mission critical profiles to be verified? And what about Urban Air Mobility trying to reinvent the way we will travel in the future but which also implies coping with stringent regulations and relying on even more efficient validation processes? Are we able to quantify the number of safety & reliability requirements which come along with the design of new generations of hybrid propulsion aircrafts, nuclear plants, space rockets that need to be checked in an extremely rigorous and timely manner? Can new technologies like Artificial Intelligence push innovation to extreme boundaries and lead to revolutionary designs unexplored until now?

Well, Siemens Digital Industries Software is relying heavily on its Xcelerator portfolio and the expertise of its teams to support industries going through these major changes with unique solutions. And this Realize Live event is the perfect opportunity to demonstrate through customer cases or product management content, where we stand today with our strategy and how this is applied to a various set of industries and products.

In particular, in this “System Simulation in the context of MBSE” session we will update you on the System Simulation Factory vision, how this vision helps solve issues related to current industry trends as mentioned in the introduction and why it is such an important element to optimize the system performance across its requirements and performance attributes, and how it further enables the best validation and verification process of our customers.

THE SIMULATION FACTORY

But first let me recall what the 4 main pillars of our System Simulation Solutions are and explain what their complementary contribution is within the Simulation Factory, my mission being that anybody reading this post can have a clear view of the issues we can solve. Our Simulation factory is composed of interoperable architecting, authoring, deployment and model and data management solutions which can integrate with any enterprise digital thread to support Model Based Systems Engineering processes. The journey basically always starts with a set of product requirements coming from marketing teams and customers, related to certification procedures, linked to the numerous variants in which this product has to be delivered … these requirements are generally stored within the PLM environment and need to be validated and verified throughout the design cycle process.

Simulation Factory

ARCHITECTING

The Simulation factory will help translate these requirements into simulation architectures, directly importing Systems Modeler architectures or using AI-based generative engineering technology to explore all possible simulation architectures which could verify the requirements and associated validation criteria. Let us take the example of the thermal management of an EV and an associated requirement corresponding to the temperature range in which the battery needs to operate.

Architecting

We know OEMs and suppliers are still investing a lot in R&D to define the best thermal management strategy and thermal management system architecture. With our AI based architecting solution, we can support the generation of all thermal management systems architectures based on the components composing the architecture (pumps, compressors, heat exchangers, thermal expansion valves, thermostat, pipes …) connected to the control and extract from the thousands of architectures that will be generated (by evaluating all possible connections combinations between all components), the ones that are compliant with the requirement to be validated. In some cases, this generative engineering technology is able to come up with unanticipated innovative architectures, making it so unique on the market.

Once the most promising thermal management simulation architecture has been detected, it is completed with interface contracts so as to really organize the process of creating the physical detailed models of the different components of the architecture and be able to connect them seamlessly. This is also a way to define connecting rule processes to have departments from the same company exchange models and integrate them together. You can also imagine it streamlines the process of integrating supplier models into an OEM integration model. The simulation architecture needs to also be “agnostic” in order to be able to integrate component models coming from different SW authoring tools possibly under the form of FMUs and to co-simulate the different compounds of the architecture. This is in a nutshell what we offer as an architecting solution.  

 AUTHORING

Once the simulation architecture is finalized, the interface contracts known and the requirements to be checked traced under the form of a Model Identity Card, we can launch the model request phase: this consists of creating the mechatronics models that are going to be consumed by the architecture in order to deliver the simulation results required to check that the battery indeed operates in the appropriate temperature range. For this we propose leading authoring solutions, multi-physics based, which will support the process of creating the 0D/1D models of any physical system (mechanical, thermal-fluids, electrical, controls). Most of the time he authoring platform is being used by Simulation experts who are going to deliver the proper model at the different stages of the design cycle, relying on a unique feature of our offer which we name modeling scalability (as illustrated in the next image).

Modeling scalability

Authoring solutions can be used at early design and detailed design stages for Model-In-the-Loop (MIL) characterization as well as in the calibration and controls strategy validation process up to creation of the executable digital twin (Software-In-the-Loop (SIL) and Hardware-In-The-Loop (HIL)). For the latter, it might be needed to rely on powerful Reduced Order Models (ROM) tools to do so, and these are also part of the Simulation Factory. Also, many additional analysis tools are delivered together with the authoring solutions to support the simulation expert in efficiently delivering and validating steady-state and dynamic models (CAD import, parameterization Apps, DOE, Linear Analysis tools, Embedded CFD, flow balancing features …)

DEPLOYMENT

Once the simulation architecture is combined with the authoring models composing it, there needs to be a way to very quickly consume these combinations in an easy-to-use environment to generate variants, scenarios or mission profiles, create customized pre and post processing.

This stage will be the one in which the real ROI of the previous mandatory stages is extracted: here indeed, the prepared architectures and models are delivered so that many non-expert users can easily perform massive numbers of analyses, and validate and verify the requirements for each variant and mission profile of the product to be designed. No need to be a simulation expert to execute this part of the work.  The deployment solution really provides companies with a way to democratize simulation tasks and have many more stakeholders supporting the validation, verification and configuration of the final product. It goes without saying that this process is supported by powerful design optimization as well as HPC and Cloud computing capabilities.

MODEL AND DATA MANAGEMENT

In the process of creating architectures, models and deployment projects, it is finally mandatory to have a model and data management infrastructure supporting the full process and in which data, architecture and models can be organized, versioned, shared and capitalized so as to ensure traceability and digital continuity, including Work-In-Progress and Enterprise model and data management layers. This is the final important and transverse key pillar of our simulation factory.
