ILVES: Accurate and Efficient Bond Length and Angle Constraints in Molecular Dynamics
Overview
Paper Summary
This computational chemistry paper introduces ILVES, a new family of algorithms for molecular dynamics simulations. ILVES improves the accuracy and efficiency of constraining bond lengths and enables constraining hydrogen bond angles, allowing for a larger time step (3.5 fs) and 1.65x faster simulations compared to current methods.
Explain Like I'm Five
Molecular dynamics simulations are like making a movie of molecules. ILVES helps make this movie faster and more accurate by locking certain bond lengths and angles, allowing scientists to simulate longer periods.
