The book A Phd Is not Enough! by Peter Feibelman is a survival guide for people embarking on a career in science. Before reading the first edition I naively thought that it was possible to drift through science without giving too much thought to such lofty notions as ‘career planning’. This book, now updated to… Read More »
Introduction This tutorial will show you how you can setup up OOMMF scripting with python. It will guide you through setting up your mif files for scripting and using python scripts to run OOMMF from the command line. The examples will show you enough to get up and running with basic scripting, and point you… Read More »
An assortment of OOMMF tips that will hopefully make your OOMMF life easier. Simulation cell size One of the easiest ways to speed up your simulation is to increase the cell size. Unfortunately this is also one of the easiest ways to get spurious results. Check out this explanation of discretization, exchange length and getting… Read More »
How to use the OOMMF periodic mesh Using the OOMMF periodic mesh (version 1.2a5) is very straightforward. You can simply replace your exising Oxs_RectangularMesh: Specify Oxs_RectangularMesh:mesh { cellsize {4e-9 4e-9 4e-9} atlas :atlas } With Oxs_PeriodicRectangularMesh, like so: Specify Oxs_PeriodicRectangularMesh:mesh { cellsize {4e-9 4e-9 4e-9} atlas :atlas periodic x } where the additional line periodic… Read More »
The Nobel Prize in Physics for 2014 was announced earlier this week, “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”. To some this is a more technically-leaning recipient than they might have liked to see, citing examples,such as the discovery of topological insulators, as being more… Read More »
