Reduced order models (ROMs) combine data and underlying first principles to accelerate physical simulations, reducing computational complexity without losing accuracy. The C++ software library called libROM provides data-driven physical simulation methods from intrusive projection-based ROMs to non-intrusive black-box approaches. The project has a new website that contains documentation and examples. Additionally, computational scientist Youngsoo Choi has recorded three user tutorials, with plans to record more in the future:
Official websites use .gov
A .gov website belongs to an official government organization in the United States.
Secure .gov websites use HTTPS
A lock (
) or https:// means you’ve safely connected to the .gov website. Share sensitive information only on official, secure websites.
