Installing micromagnetic software can be a challenge. There are can be complex dependencies and it’s not always clear how to get a working system. I recently stumbled across the virtual micromagnetics project which provides an entry point for researchers wanting to exploit virtual machines for micromagnetics. I was intrigued by this idea – virtualisation plays… Read More »
Once you have installed OOMMF, and ran some simulations, you will at some point probably want to produce some images of your simulation outputs. It’s not obvious how to do this, so this post explains how you can make images from oommf outputs using the command line tool ‘avf2ppm’ that comes with OOMMF. OOMMF Vector… Read More »
Installing OOMMF is a multi-step process which can be a bit fiddly, particularly on Linux systems. I would normally just work through the installation steps separately, but was inspired by the Virtual Micromagnetics project to write an OOMMF install script. This OOMMF install script is contains the steps needed to install OOMMF on a Debian… Read More »
It is often more useful to think of applied field in terms of polar coordinates – with an angle and a magnitude. By default the Zeeman term in OOMMF takes inputs in cartesian coordinates – i.e. x, y and z components. In many situations this is fine, but there are times when polar coordinates make… Read More »
In this post I show you how to simulate an OOMMF hysteresis loop. You can follow this tutorial with more or less any OOMMF oxsi mif file, but I will be using a version of the oxsi exchspring.mif example file that comes with OOMMF, modified to automatically display some outputs.
