For accurate insights on a complex material, it's crucial to have an understanding of its meso and micro-scale physics and structure formation. Fluid flow at the macroscale (visible to the naked eye) is often simulated using computational fluid dynamics (CFD). However, materials developed today have functions emerging from various physical processes across broad length and time scales.
Take emulsions for example. Surfactant behavior at interfaces is a microscopic process, but behavior of emulsion droplets in flow is at the mesoscopic level. Simulating complex fluids and materials therefore requires modeling through both molecular and meso scales - multiscale modeling.
We have adopted this approach, using two core simulation techniques; Smoothed Particle Hydrodynamics (meso), and Molecular Dynamics (molecular).
