Altair simulation-driven design changed product development forever, enabling engineers to reduce design iterations and prototype testing. Increasing scientific computing power expanded the opportunity to apply analysis, making large design studies possible within the timing constraints of a program. Now engineering adoption of AI is transforming product development again. The combination of physics-based simulation-driven design with machine learning, leveraging the latest in high-performance computing, enables teams to explore more and identify high-potential designs – while rejecting low-potential concepts – even earlier in development cycles.

Meaningful Models

The right model, for the right decision, at the right time.

Relevant and timely models for concept design, product engineering, and detailed analysis need different levels of complexity and data. Altair understands the requirements of meaningful models throughout a program and across disciplines to increase decision-making confidence and speed by enabling product performance target exploration, trade-off evaluations, and ‘what if’ studies.

By combining computationally efficient reduced-order models and detailed CAE analysis with process automation of repetitive and tedious tasks, Altair provides workflows for early system models, to mixed-fidelity simulations and multiphysics validations, across domains including electrification or advanced manufacturing.

Physics-based simulation-driven design augmented with machine learning-based AI-powered design has the potential to create high-potential designs earlier in development cycles. Altair DesignAI enables organizations to scale existing expertise and realize the value of archived simulation data to solve the most challenging design and engineering problems faster.
