Oxs Extension Modules

This page contains links to extensions to the OOMMF Oxs (OOMMF eXtensible Solver) 3D micromagnetic solvers, Oxsii and Boxsi. These extensions were not developed by OOMMF personnel, and NIST assumes no responsibility whatsoever for its use by other parties, and makes no guarantees, expressed or implied, about its quality, reliability, or any other characteristic.

No extension on this page is included in any official OOMMF release, source nor binary. At the time of this writing, all Oxs extensions are released as source code only; installation of these extensions requires a C++ compiler compatible with OOMMF. The installation sections of the OOMMF User's Guide contain information on C++ compiler requirements and detailed build instructions.

General Oxs extensions installation instructions

1. Download the Oxs extension software and install (copy) it into the directory

   oommf/app/oxs/local

   Depending on the extension, additional supporting software libraries may also need to be installed on your system. Check the documentation for the Oxs extension you are installing for details.

2. (Re)build the OOMMF software. If you are using a binary distribution of OOMMF, you should first destroy the pre-built executables by running the following command from the OOMMF root directory (oommf/):

   tclsh oommf.tcl pimake distclean

   If you originally built from source, and have not changed your compiler nor made other significant changes to your build environment, then you may omit the "pimake distclean" step. To compile the Oxs extension software and link it into the Oxs executable, run the command

   tclsh oommf.tcl pimake

   from either the oommf root directory oommf/ or the Oxs directory oommf/app/oxs/.

3. Create MIF 2.x files that contain Specify blocks for the new Oxs extension class. See the documentation of the extension class for details.
