OOMMFOOMMF 1.0


Beta releases of OOMMF 1.0

This is the first official release of the OOMMF micromagnetic software. To reflect that this is a research code, and not intended as a commercial product, it is labeled a "beta" release. However, we are treating this as a stable release. The 24-Feb-2000 version is the final 1.0 release. All OOMMF 1.0 users are encouraged to migrate to the 1.1 release. See the CHANGES file for a summary of the differences between releases.

We are maintaining a bibliography of papers using OOMMF. If you publish results using this software, we would appreciate an email with the citation, so we can include it in our list.

Be sure to retain the directory structure when unpacking. Then check the README file in the oommf subdirectory, and the online documentation and quickstart pages. If you have questions, please contact michael.donahue@nist.gov.

This code requires Tcl/Tk. We recommend the latest stable (i.e., not alpha or beta) release of Tcl and Tk concurrent with your release of OOMMF (except as noted). OOMMF software does not support any alpha or beta releases of Tcl/Tk, and each release of OOMMF may not work with later releases of Tcl/Tk. Check the release dates of both OOMMF and Tcl/Tk to ensure compatibility. As a convenience, we have made some pre-built Tcl/Tk Windows NT/Alpha binaries available.

Important note: If you are using one of the pre-compiled binary releases, then the version of Tcl/Tk on your system must match the Tcl/Tk version against which the OOMMF binaries were built. For example, if you have Tcl/Tk 8.0.5 installed, then you should download the build of OOMMF for Tcl/Tk 8.0.x.
