Explore What’s New in Simcenter Prescan 2302

With the Simcenter Prescan release 2302 from Siemens Digital Industries Software, the company is enabling the ability for users to build and validate autonomy algorithms belonging to various mobility platforms across industries. This is done through improved sensor simulation realism, the possibility to model agricultural, industrial and other multiple axle vehicles, easier traffic simulation and AV software stack coupling and cost-effective massive validation, according to Siemens.

Measured Material Library

Siemens has introduced seven measured materials for the Simcenter Prescan car models in the 2302 release. These are: black, white and metallic gray car paints and blue denim, blue polyester, black cotton and retroreflective paint. The bidirectional reflectance distribution functions (BRDFs) of these materials have been measured at 850 nm, 905 nm and 1550 nm wavelengths in a controlled lab environment. The results of these measurements were then processed and incorporated into Simcenter Prescan.

Users can now import their models via the Simcenter Prescan Model Preparation Tool, and assign these measured materials, as well as other materials from the Simcenter Prescan material database, to any part of their models that they desire.    

Camera Sensor Simulation

In the 2302 release, Simcenter Prescan Physics-Based camera is enhanced with a new functionality that allows photorealistic dynamic raindrop simulation on glass. The direction and the rolling speed of the rain droplets on the glass can be adjusted during runtime.

With this new addition, Simcenter Prescan users can:

1. perform hardware and software in the loop testing to examine the success of their sensors to trigger windshield wipers.
2. test/train their machine learning algorithms against/with synthetic datasets that contain raindrops on glass.

Simulate Multi-Axle Vehicles

Driving assistance and automation technologies are being increasingly adopted by freight delivery companies. Simcenter Prescan enables these companies to develop and test these systems virtually.

Simcenter Prescan users can add truck models with more than two axles into the simulation environment via the Model Preparation Tool.

The contact sensor of Simcenter Prescan has been enhanced to automatically provide the contact information of any number of wheels during the simulation. To realistically model the motion of these vehicles, the user can integrate high-fidelity vehicle dynamics models such as TruckSim. 

Autonomous Vehicle Future

Simcenter Prescan now enables autonomous vehicle (AV) developers to quickly start testing and validating their AV software. The capability is achieved through a data bridge, which can be configured for any user-defined AV stack. AV developers can test their software using Simcenter Prescan without needing to modify their software stack.

Cost-Effective Massive Simulation 

Organizations often partner with one cloud service vendor or leverage cloud resources from multiple vendors. Simcenter Prescan360 caters to both strategies by embracing a multi-cloud support model. Massive simulations enabled by Simcenter Prescan360 can now be run on Google Cloud Platform, in addition to Microsoft Azure, Amazon AWS and on-premise cluster. Simcenter Prescan360 can coexist in your cloud/on-premise ecosystem with other applications, leveraging capabilities of the cloud vendor/ on-premise infrastructure.

Simcenter Prescan360 leverages managed and proprietary services from respective cloud vendor for automated scale-up and selection of compute-resources based on the simulation payload. 

Optimizing for Fuel Efficiency

The automotive industry is facing a demand to improve fuel efficiency and comply to emissions regulations. With the right set of integrated tools, Simcenter enables you to frontload these risks and tackle them at an early phase with software in the loop method. In Simcenter workflow, the digital twin of your vehicle, control system and traffic scene is first modeled in Simcenter Prescan and its Sumo traffic simulator. This model can estimate the fuel consumption and particulate emissions during the virtual drive.

Simcenter HEEDS, Siemens solution for Multi-domain optimization, will optimize the controller parameters for minimal fuel consumption while adhering to the emissions constraints. Native integration between Simcenter HEEDS and Simcenter Prescan makes model parameterization more user-friendly, and allows the user to dynamically switch between desktop and cloud execution.

Whats Next?

The company is working on adding new platform support for our Simcenter Prescan360 users, enhancing the sensor simulation capabilities for accurate sensor digital twins, unified weather experience for all sensors and closing the loop for Advance Driver Assistance Systems/Autonomous Vehicle validation with an updated driver model.
