Altair® romAI™

Reduced Order Modeling (ROM) and System Identification from Simulation & Test Data


Generate Static or Dynamic Models

Our romAI is a game-changing artificial-intelligence (AI) powered technology within Altair® Twin Activate™. With it, organizations can generate static or dynamic ROMs from simulation and test data and run whole-system analyses at phenomenal speed. Leveraging ROMs for system evaluation speeds up computationally expensive simulations, such as discrete element method (DEM), computational fluid dynamics (CFD) and finite element (FE) analyses, leaving more room to test ideas and optimize system performance. This extremely efficient approach helps organizations reduce time-to-market, slash cost, and reach sustainability goals faster. 

An indispensable asset to your model-based development workflows, romAI serves many purposes: digital twin creation and deployment; faster optimization and multi-disciplinary analysis; test data processing for system identification applications, and better real-time simulation accuracy. It supports popular formats, including Functional Mock-up Interface (FMI) standard, C code, and dynamic link library (DLL), for exporting to third-party software or hardware-based applications.
