Visualizing Crystal Structures: An interactive group classroom activity
11 Nov 2016 | Teaching Materials | Contributor(s): Susan Gentry, Tanya Faltens
Overview This learning activity guides students through the visualization of three-dimensional crystal structures using the software package Ovito. Students work in groups manipulating crystal structures on their personal computers, ranking the planar densities of the (100), (110), and (111) planes in face-centered cubic (FCC) and NaCl crystal structures. The activity can be performed in a 50 minute lecture session, in a lab or discussion section, or as homework. Ovito is an...
How to Create Atomic Planes in FCC, NaCl and Simple Cubic Structures
27 Oct 2016 | Teaching Materials | Contributor(s): Tanya Faltens
This step by step guide shows how to create atomic planes in some common crystal structures. The crystal structures can be sliced along the planes, and the atomic packing of each plane investigated. Links to saved simulations of each of the planes and structures are included. These instructions should enable the user to create meaningful representations of many Miller planes in the numerous materials and structures available in Crystal Viewer.
nanoHUB Simulation Activity - Orientations of Common Single Crystal Substrates
07 Jun 2016 | Teaching Materials | Contributor(s): Tanya Faltens
NEW Version 2! (10/17/16) Now includes a link to the saved set of simulations, that can be shared instantly with any nanoHUB user. Other minor edits to update the activity and fix errors. In this activity, you will use Crystal Viewer to create crystal structures with surfaces that are specific planes, specified by Miller indices, allowing you to visualize and compare the atomic arrangements and numbers of “dangling bonds” on the different surfaces.
OOMMF FTUG: Object Oriented MicroMagnetic Framework First Time User's Guide
24 Mar 2016 | Teaching Materials | Contributor(s): Tanya Faltens
OOMMF is the Object Oriented MicroMagnetic Framework, which is a powerful research-grade simulation tool for modeling the response of materials to applied magnetic fields that was developed by Dr.s Mike Donahue and Don Porter in the Information Technology Laboratory at the National Institute of Standards and Technology (NIST). This first-time user guide demonstrates how to download, read and run an OOMMF example problem file in OOMMF running on nanoHUB, and is written for the...
Exploring Materials Properties with Nanomaterial Mechanics Explorer Structure Files
This document describes how to generate and download simulation output files from the Nanomaterial Mechanics Explorer on nanoHUB and view them locally using OVITO. This can be particularly useful for more advanced manipulations of the trajectory files, and for sharing files with others, such as in a classroom environment.

What are wiki pages?
Wiki pages are user-written articles on a range of subjects. Any contributor or a group of contributors can create (and own) new articles, and there can be multiple articles on the same wiki, each written by a different author.
