Simcenter PhysicsAI

Simcenter PhysicsAI is a simulation acceleration solution from Siemens Digital Industries Software that leverages AI surrogate models trained on high-fidelity simulation data to help engineering teams explore design spaces in real time. Compared with traditional solver-based simulations, it can provide accelerated data-driven insights at a fraction of the time — in some cases up to 1,000x faster. At the core of Simcenter PhysicsAI is geometric deep learning (GDL) technology, which operates directly on meshes and CAD geometries without requiring manual feature engineering. This enables the software to learn complex relationships between shape and physical performance across multi-physics domains - including structural mechanics, computational fluid dynamics (CFD), thermal, electromagnetic and manufacturing analysis. Using data from Siemens and third-party solvers, engineers train AI models from either existing simulation data or new data generated through design of experiments (DOE) studies. Built-in validation tools and error metrics ensure these models accurately capture physical performance trends, giving engineers the confidence to make critical design decisions before predicting the performance of previously unseen geometries. Simcenter PhysicsAI supports a no-code, intuitive workflow that democratizes AI-powered simulation across multidisciplinary engineering teams, making advanced AI capabilities accessible without requiring deep expertise in machine learning or data science. It integrates seamlessly within the Simcenter portfolio - including Simcenter STAR-CCM+, Simcenter Hypermesh, Simcenter Simlab, and Simcenter Inspire - fitting naturally into existing engineering workflows without disruption. Simcenter PhysicsAI is built for simulation engineers, CAE analysts, design engineers, and data scientists working across industries where engineering performance, product reliability, and time-to-market are critical. It is particularly well-suited for organizations that already run large volumes of high-fidelity simulations and want to leverage that data investment to build scalable AI-driven workflows. By shifting early-stage screening from computationally intensive solver runs to AI inference, organizations can accelerate innovation while significantly reducing engineering costs.
