👉 The Interact Fluid Dynamics (IFD) is a computational method used to simulate the behavior of fluids and their interactions with solid surfaces, particularly at the molecular level. It combines principles from fluid dynamics, molecular dynamics, and continuum mechanics to model how fluids flow around and interact with complex geometries, such as porous materials or rough surfaces. By solving the Navier-Stokes equations alongside molecular interaction potentials, IFD captures both macroscopic fluid flow characteristics and microscopic interactions between fluid molecules and the solid substrate, providing detailed insights into phenomena like slip flow, viscous dissipation, and surface roughness effects. This approach is especially valuable for studying systems where traditional continuum models fail, such as in nanofluidic devices or biological environments with heterogeneous surfaces.
