Multiscale and multiphysics modeling and simulation methods are nowadays essential tools for analyzing complex systems. For example, engineers often need to simulate large scale structures where the micro-mechanical properties of constituent materials greatly affect the overall behavior of the system. As such, the micro-structure and mechanical properties need to be introduced explicitly in the analysis procedure. Multiphysics plays an equally strong role is in the design of subsystems and how they interact with other subsystems and systems. One example is MEMS (microelectromechanical systems) which typically include small moving parts such as wheels, rotors, levers, and linkages, and how they operate within larger systems. Other examples include the creation of "designer materials" tailored for specific environments, as well as the simulation of nanoscale mechanics of cancer cells and how that is being extended to medical treatment devices and methods.Traditional simulation methods such as FEA are consequently pushed to their limits; fine detailing is required to represent accurately the actual response leading to prohibitive computational costs. This conference aims to introduce the essential principles of multiscale and multiphysics analysis for engineering problems and how to communicate micro-scale modeling and simulation information onto the macro-scale level, leading to reduced order, yet accurate, models. Focus will be on presenting the key benefits and limitations of multiscale and multiphysics analysis through illustrious examples pertaining to actual industrial applications.This material was presented at the “Multiscale and Multiphysics Modeling & Simulation - Innovation Enabling Technologies" Conference, hosted by NAFEMS Americas on March 28th-29th, 2017 in Columbus, OH.
