hPF-MD.jl: Hybrid Particle-Field Molecular-Dynamics Simulation
2021-07-28 , Blue

We introduce an efficient framework of molecular-dynamics simulations (hPF-MD), using a density-functional-based formalism to compute the non-bonded interactions between particles. hPF.jl is motivated to leverage the advantages of Julia, an interpreted language designed to achieve high-performance, statically compiled programming languages and the extensive computing community.


In this talk, we will give (1) a brief overview of the hPF-MD method, (2) example systems compared with results from existing hPF-MD packages and standard MD method, and (3) advantages and extensibility of their Julia implementations.
