OOMMF OOMMF 2.0

Beta release of OOMMF 2.0

This is the latest beta release of the OOMMF micromagnetic software. The intent is to treat this release as interface stable and limit further changes in the 2.0 releases to bug fixes. This should be a solid base for extensions to reliably build on, while development continues in a new alpha series.

Several alpha releases are also available here, but they should be considered matters of historical interest now. Use of the beta releases is recommended.

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.

Starting with the 2.0 series, OOMMF requires C++11 and Tcl/Tk 8.5 (or later). The C++ requirement is met by GNU g++ 4.7, or recent releases of any of the other popular C++ compilers. For Tcl/Tk we recommend the latest stable (i.e., not alpha or beta) release concurrent with your release of OOMMF unless otherwise 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.

Important note 1a: If you are using one of the pre-compiled binary releases of OOMMF, 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 8.6.6 installed, then you should download the build of OOMMF for Tcl/Tk 8.6.x.

Important note 1b: ActiveState changed build tools between their Tcl/Tk 8.6.4 and 8.6.6 releases. This resulted in a change to the naming convention for the Tcl/Tk DLL's. In ActiveTcl 8.6.4 the Tcl and Tk libraries are named tcl86.dll and tk86.dll. In ActiveTcl 8.6.6 the names are tcl86t.dll and tk86t.dll. The OOMMF 29-Sep-2017 64-bit Tcl/Tk 8.6 binary was built using the new convention. A workaround if you need to mix an executable using one convention with a DLL using the other is to simply make copies of the DLL's with the other naming convention. For example, copy c:\Tcl\bin\tcl86.dll c:\Tcl\bin\tcl86t.dll.

Important note 2: Extensions on the Oxs Extension Modules page that are included inside an OOMMF release are current at the date of release, but check the links on the extension page for documentation, news, and more recent updates to the extensions.

Note for recent macOS users: The version of Tcl/Tk (8.5.9) that comes with macOS doesn't display Tk widgets properly in macOS Mojave (10.14) or later, as can be demonstrated with a simple Tcl script. To use OOMMF on recent releases of macOS you will need to install Tcl/Tk 8.6.9 or later from a third-party source such as MacPorts or HomeBrew, and then build and run OOMMF using that Tcl/Tk installation.
