Title: ZIBgridfree: efficient conformational analysis by partition-of-unity coupling.
Authors: Bujotzek, Alexander; Schütt, Ole; Nielsen, Adam; Fackeldey, Konstantin; Weber, Marcus
Abstract: Obtaining a sufficient sampling of conformational space is a common problem in molecular simulation. We present the implementation of an umbrella-like adaptive sampling approach based on function-based meshless discretization of conformational space that is compatible with state of the art molecular dynamics code and that integrates an eigenvector-based clustering approach for conformational analysis and the computation of inter-conformational transition rates. The approach is applied to three example systems, namely $$n$$ -pentane, alanine dipeptide, and a small synthetic host-guest system, the latter two including explicitly modeled solvent.
