Area of Science:

  • Computational physics
  • Mesoscopic modeling
  • Fluid dynamics

Background:

  • Molecular dynamics (MD) simulations provide detailed microscopic insights but are computationally expensive.
  • Existing mesoscopic methods like dissipative particle dynamics (DPD) offer a balance but can lack direct links to underlying physics.
  • Bridging the gap between microscopic and macroscopic scales is crucial for complex system simulations.

Purpose of the Study:

  • To derive a novel mesoscopic modeling and simulation technique.
  • To establish a direct link between molecular dynamics (MD) and mesoscopic descriptions.
  • To develop a method capable of handling multiple length scales simultaneously.

Main Methods:

  • Systematic coarse-graining of molecular dynamics (MD) to derive mesoscopic particle interactions.
