Multi-scale Modeling

A computational approach that integrates multiple models operating at different spatial and temporal scales to understand complex systems holistically.

Multi-scale Modeling

Multi-scale modeling is a sophisticated computational approach that bridges multiple levels of system organization, from microscopic to macroscopic scales, to create comprehensive understanding of complex phenomena. This methodology has become increasingly crucial in modern scientific computing and complex systems research.

Core Principles

Scale Integration

  • Connects models across different spatial scales (nano to macro)
  • Links processes across varying temporal scales (microseconds to years)
  • Maintains mathematical consistency between scale transitions

Model Hierarchy

  1. Atomic/molecular level (quantum mechanics)
  2. Mesoscale (statistical mechanics)
  3. Continuum level (classical physics)
  4. System-wide behavior
