libROM is a free, lightweight, scalable C++ library for data-driven physical simulation methods. It is the main tool box that the reduced order modeling team at LLNL uses to develop efficient model order reduction techniques and physics-constrained data-driven methods. We try to collect any useful reduced order model routines, which are separable to the high-fidelity physics solvers, into libROM. Plus, libROM is open source, so anyone is welcome to suggest new ideas or contribute to the development. Let's work together for better data-driven technology!

Features

• Proper Orthogonal Decomposition
• Dynamic mode decomposition
• Projection-based reduced order models
• Hyper-reduction
• Greedy algorithm

Many more features will be available soon. Stay tuned!

libROM is used in many projects, including BLAST, ARDRA, Laghos, SU2, ALE3D and HyPar. Many MFEM-based ROM examples can be found in Examples.
