Grain Boundary Motion Analysis
08 Aug 2018 | Contributor(s):: Jeremy Seiji Marquardt, Xiaorong Cai, Marisol Koslowski
Grain growth is a mechanism to relax residual stresses in thin films. These grains grow out of the thin film surface and are known as whiskers. These whiskers can cause short circuits, so developing scalable and cost effective solutions would increase the reliability and...
Geometric Multigrid for MHD Simulations with Nedelec Finite Elements on Tetrahedral Grids
04 Feb 2016 | | Contributor(s):: Chris Hansen
The Magneto-HydroDynamic (MHD) model is used extensively to simulate macroscopic plasma dynamics in Magnetic Confinement Fusion (MCF) devices. In these simulations, the span of time scales from fast wave dynamics to the desired evolution of equilibrium due to transport processes is large,...
On the Design of a Finite Element Multigrid Solver for Mimetic Finite Difference Schemes
04 Feb 2016 | | Contributor(s):: Carmen Rodrigo
The focus of this work is to study the relation between mimetic finite difference schemes on triangular grids and some finite element methods for two model problems based on curl-rot and grad-div operators. With this purpose, modified Nédélec and Raviart-Thomas finite element...

IMA 2013 UQ: Foam Property Prediction from Process Modeling
28 May 2014 |
We are developing computational models to elucidate the injection, expansion, and dynamic filling process for polyurethane foam such as PMDI. The polyurethane is a chemically blown foam, where carbon dioxide is produced via reaction of water, the blowing agent, and isocyanate. In a competing...

Modeling the quantum dot growth in the continuum approximation
08 Jan 2011 | | Contributor(s):: Peter Cendula
Quantum dots can grow spontaneously during molecular beam epitaxy oftwo materials with different lattice parameters, Stranski-Krastanow growth mode.We study a mathematical model based on the continuum approximation of thegrowing layer in two dimensions. Nonlinear evolution equation is solved...

Experiment vs. Modelling: What's the problem?
05 Jun 2009 | | Contributor(s):: William L. Barnes
Progress in plasmonics has been greatly assisted by developments in experimental techniques and in numerical modelling. This talk will look at some of the difficulties that emerge when comparisons are made between experiment and theory. Through the use of four examples I will illustrate what some...
Microstructural Design of Electrically Active Materials and Devices Through Computational Modeling: The OOF Project
out of 5 stars
20 Jan 2009 | | Contributor(s):: R. Edwin Garcia
We present an overview of a public domain program, the Object Oriented Finite Element analysis (OOF), which predicts macroscopic behavior, starting from an image of the microstructure and ending with results from finite element calculations. The program reads an image (or a sequence of images)...
