If you work with molecular dynamics (MD) or enhanced sampling, you’ve likely encountered the challenge of rare events—like protein folding or chemical reactions—that occur beyond standard simulation timescales.

Demystifying FDES & NNF: A Smarter Way to Explore Molecular Energy Landscapes fdes nnf

Two advanced acronyms gaining traction are (Frequency Domain Enhanced Sampling) and its core component, the NNF (Nonlinear Normalization Function). Here’s a breakdown of what they are and why they matter. What is FDES? FDES is a biasing method used to accelerate the exploration of a system’s potential energy surface. Unlike traditional methods (e.g., metadynamics or umbrella sampling) that add repulsive potentials in real space or along collective variables, FDES works in the frequency domain . If you work with molecular dynamics (MD) or
