We present five optimized solutions for CAE, simulation, and computation, such as increased efficiency in vehicle development and new possibilities for immersive engineering.

Simulation for Efficient Vehicle Development

The Car-Maker product family enables extensive tests, which are essential for today's vehicle development, to be conducted largely virtually, making them cost- and time-efficient. In particular, the development of driver assistance and automation systems (ADAS & AV) presents challenges for automakers and suppliers, which the Release 14.0 of the Car-Maker product family from IPG Automotive addresses with extensive innovations.

The development of these systems requires testing a wide range of realistic scenarios. While highway simulations focus on various traffic densities and driving maneuvers, urban traffic additionally requires consideration of interactions with pedestrians. Release 14.0 of the Car-Maker product family enables the flexible control of both autonomous vehicle traffic and pedestrians.

Intelligent And Intuitive Working in XR

The current version of Hololight Space has been developed to help engineers and designers work faster, smarter, and more intuitively than ever before. Version 2025.0.0.0 offers significant improvements for both AR and VR, with a focus on realistic workflows, enhanced user-friendliness, and broader hardware support. In AR, the new quick menu enables more efficient access to tools with fewer clicks. All functions are now consolidated in one place.

Immersive Engineering in Focus

Siemens Digital Industries Software has introduced the latest updates for its NX and NX X software from the Designcenter suite for product development software. These include immersive engineering for mixed-reality design and collaboration, new functions for manufacturing optimization, CAD-integrated flow simulation, and a new AI copilot for design.

• In addition to the features of NX Immersive Designer, which allow designers and engineers to create, view, and edit 3D CAD designs in Virtual Reality or Augmented Reality, the latest updates introduce NX Immersive Collaborator. This enables colleagues, partners, and other stakeholders to collaborate in the same virtual reality space. Collaborative sessions can be launched directly from the NX interface without the extensive preparatory work typically associated with VR collaboration and offer a full range of design review tools for measuring, evaluating, and annotating individual parts or entire assemblies.
• The new Design Copilot NX, delivered with the latest update, leverages Siemens' robust learning resources and offers an AI-based natural language interface to help users accelerate their learning—whether they are new to the software or experienced users looking to expand their knowledge and explore new features. By utilizing natural language inputs and queries, the NX Copilot functions enable users to quickly and efficiently find answers to technical questions, best practices, and documentation.

Tool for Fast Parametric Design Analyses

Parametric studies are a common practice in engineering calculations. They involve altering various parameters in the model to examine their impact on the final calculation results. Parametric analyses are typically conducted using a type of scripting or programming language. Kisssoft supports parametric analysis through its integrated scripting language or a COM interface compatible with popular programming languages such as Python, Visual Basic, and others.

In addition to many other variables, the tool offers the ability to modify shaft geometry, forces, and bearings by calling the specific function Set-Element-Data (elementName, parameterName, newValue). This enhancement simplifies the variation of any parameter within the shaft model. A typical application is, for example, evaluating how the bearing position affects the rolling bearing's lifespan, as well as analyzing the effects of clearance or preload.

Thanks to the 6-DoF Platform, High Dynamics Can Also Be Simulated Accurately

Hexa-Rev from VI-Grade is a driver-in-the-loop (DiL) motion platform that, thanks to a revolutionary mechanical concept with a direct-drive architecture, aims to provide unprecedented system responsiveness, motion efficiency, and simulation quality.

While conventional systems often reach their limits with combined movements, Hexa-Rev, through a new mechanical and kinematic concept, offers significantly expanded degrees of freedom. This allows for more realistic and accurate simulation of vehicle behavior in highly dynamic scenarios, such as braking in corners or accelerating through a chicane.
