OOMMF Roadmap

Overview of the OOMMF releases

• OOMMF 1.0 This is the first released version of OOMMF. The initial alpha release was made on 15-Jan-1998, the first beta on 20-Oct-1998, and the final beta (1.0b3) on 24-Feb-2000. OOMMF 1.0 consists of the following major components:

  Bootstrap application oommf.tcl

  Provides a uniform and simplified interface for running applications from the command line. If no command line arguments are specified, oommf.tcl will bring up mmLaunch by default.

  mmLaunch

  A graphical user interface (GUI) for launching, monitoring, and controlling other OOMMF applications.

  mmProbEd

  A windowing interface for creating and editing micromagnetic problem descriptions in the Micromagnetic Input Format (MIF).

  mmSolve2D

  A micromagnetic computation engine for solving problems defined on a two-dimensional mesh of square cells representing three-dimensional spins. Reads MIF files for input, and generates OOMMF Data Table (ODT) and OOMMf Vector Field (OVF) output data.

  mmDataTable

  Tabular data display widget, accepting ODT style input.

  mmGraph

  Generates and displays xy-plots from ODT style input.

  mmDisp

  Displays two-dimensional spatial distributions of three-dimensional vectors (i.e., vector fields). Accepts OVF input.

  mmArchive

  Provides automated vector field and data table storage.

  OOMMF Batch System (OBS)

  Tcl script level control for managing multiple micromagnetic problem runs.

  Pimake (Platform Independent Make)

  Tcl-only application for building OOMMF from source.

  mmHelp

  A Tcl/Tk-only documentation browser. OOMMF documentation is in HTML (Hyper Text Markup Language) format, and may alternatively be read using any web browser.

  User's Guide

  Documentation in both PostScript and HTML format.

  
  

• OOMMF 1.1 Initial alpha release made on 28-Apr-1999, beta releases on 4-Apr-2000, 2-Oct-2001, and 15-Jan-2004. Notable enhancements over OOMMF 1.0 include:

  Bootstrap application oommf.tcl

  Moved to OOMMF root directory. Changes in command line arguments for improved uniformity.

  mmSolve

  New ConstMag "average H" demag kernel. Time stepping control. Changed Zeeman energy zero-offset. Creates log files and supports -restart command line option. Raises error if cell size does not divide part dimensions.

  mmGraph

  Supports two y-axes.

  mmDisp

  Data value scaling. Divergence and color-wheel displays.

  mmProbEd

  Improved default material parameter values.

  Command line utilities

  Command line interfaces for repetitive tasks. These include

  • avf2ppm: Creates bitmaps from vector fields.
  • any2ppm: Bitmap file format conversion.
  • avf2ovf: Vector field file format conversion.
  • mag2hfield: Calculates component H fields from problem specification (.mif) and magnetization file (.omf).
  • odtcols: Extracts column subsets from ODT data table files.

  User's Guide

  Available in PDF format as well as PostScript and HTML.

  Support for Mac OS X

  
  

• OOMMF 1.2 Initial alpha release made on 18-Nov-2000. First beta release 30-Sep-2016. Notable enhancements over OOMMF 1.1 include:

  OOMMF eXtensible Solver (OXS)

  3D mesh. Arbitrary number of energy terms. Pointwise variation of material constants. New input file format (MIF 2.0). Designed to be extended at the C++ class level.

  Command line utilities

  • avf2odt: Making Data Tables from Vector Fields
  • avf2ps: Making PostScript from Vector Fields
  • avfdiff: Vector Field File Difference
  • crc32: Cyclic Redundancy Check
