Abstract

Weidlinger Associates Inc and Cornell University propose to create a Computational Environment for Simulation of Micro/Nano-Devices (NanoSE). We will develop a fully integrated software tool that will enable army researchers and design engineers to simulate the behavior of devices, such as multi-function sensors, with extreme thermal and mechanical loading typical of battlefield conditions. The resulting tool will allow for seamless incorporation of physical effects on multiple length and time scales in one integrated simulation. Mathematically consistent and numerically stable algorithms will be evaluated to achieve full coupling of a flexible, modern and powerful molecular dynamics code with a proven, industrial strength, explicit finite-element wave propagation simulation package. We will evaluate an option to couple the explicit finite-element code to a high-order adaptive hp-version finite element code to incorporate macroscopic behavior on a even larger length scale. Key to the efficiency of our integrated multiscale modeling package is the utilization of an adaptive software, adaptive modeling, adaptive discretization (A-SMD) approach.
