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 »
When doing micromagnetic simulations it is easy to end up with hundreds of output files, so part four of this OOMMF Tutorial covers some of the tools available for analysing OOMMF data. This list isn’t exhaustive – if I’ve missed out your favourite – please leave a comment! OOMMF outputs two types of data: vector,… Read More »
Data from micromagnetic simulation software has become a common sight in research papers – either as standalone work as support to experimental data. There are now quite a few choices for which micromagnetic simulation software to use. This list gives an overview of the micromagnetic solver packages I’m aware of. They’ve all got their own… Read More »
Part 3 of this getting started tutorial for OOMMF introduces mif problem files and some of the example files that come with OOMMF distributions. Part 1 covered downloading and installing OOMMF. Part 2 covered running OOMMF. Search for Micromagnetics on Amazon [Sponsored Link] mif Files Micromagnetic calculations in OOMMF are set up in a mif… Read More »
