Highlights of Crash & Safety Simulation with VPS

These are the main VPS software features that empower users to deliver trustworthy simulation results at speed, efficiency, and cost-effectiveness:

  • Fast solver facilitates more simulation runs in the available time and delivers reliable simulation results quickly and early.
  • A single core model where multiple types of simulation can be applied to the same common 3D model, saving time, enabling concurrent engineering, and resulting in a more optimized end product.
  • Built-in library of modular material models and physical properties provides highly accurate performance predictions ensuring early confidence in compliance with safety standards.
  • Combining Finite Point Method (FPM) technology with the VPS structural dynamics solver for a more precise prediction of liquid or gas flow effects on the vehicle structure.
  • Workflow automation & model quality check via Visual Environment for greater efficiency in the simulation process and higher reliability of simulation results
  • Multi-scale modeling combines detailed micro-level assessment with a coarser macro-level model, achieving a balance between accuracy and time/cost efficiency
  • Continuous software innovation with advanced model order reduction capabilities and smart machine learning technology, enabling engineers of all skill levels to efficiently explore design spaces, prioritize variables, and optimize vehicle safety, weight, cost, crash repairability, and safety ratings within a limited timeframe
  • Achieve enhanced realism in crash simulations through integration with our manufacturing simulation software such as Sysweld, and SimulationX, our system simulation software. On this basis, engineers can accurately assess conditions as manufactured and the impact of active safety systems in crash scenarios.

Elevate Crash Testing to New Heights with Unparalleled Speed & Precision

Virtual crash simulation is becoming more prevalent in replacing physical crash testing for regulatory certification because of its enhanced accuracy, lifelike human body models, and the capability to digitally predict intricate scenarios. This shift reduces the need for hardware prototypes and testing in product development, fostering financial sustainability, and minimizing carbon emissions in new business models.

VPS gives crash engineers round-the-clock access to the complete virtual vehicle and their dedicated digital crash laboratory.
