What are the limitations of DMD in high-speed reacting flows?

Dynamic mode decomposition (DMD) is a dimensionality reduction algorithm developed by Peter J. Schmid and Joern Sesterhenn in 2008. ... Dynamic mode decomposition of. nonequilibrium electron-phonon. dynamics: accelerating the. fi. rst-. principles real-time Boltzmann equation. Check for updates. Dynamic mode decomposition (DMD) is a recently developed method focused on discovering coherent spatial-temporal modes in high-dimensional data collected from ... Jul 25, 2016 ... The DMD converts a dynamical system into a superposition of modes whose dynamics are governed by eigenvalues. Jun 10, 2024 ... In summary, we have introduced a data-driven approach based on DMD to accelerate first-principles calculations of nonequilibrium electron ... Abstract.
