Micromagnetic Problem Editor: mmProbEd

mmProbEd Screen Shot

The application mmProbEd provides a user interface for creating and editing micromagnetic problem descriptions in the Micromagnetic Input Format (MIF 1.1). mmProbEd also acts as a server, supplying problem descriptions to running mmSolve2D micromagnetic solvers.

mmProbEd may be started either by selecting the mmProbEd button on mmLaunch, or from the command line via

tclsh oommf.tcl mmProbEd [standard options] [-net <0|1>]

-net <0|1>
Disable or enable a server which provides problem descriptions to other applications. By default, the server is enabled. When the server is disabled, mmProbEd is only useful for editing problem descriptions and saving them to files.

The menu selection File|Open... displays a dialog box for selecting a file from which to load a MIF problem description. Several example files are included in the OOMMF release in the directory oommf/app/mmpe/examples. At startup, mmProbEd loads the problem contained in oommf/app/mmpe/init.mif as an initial problem. Note: When loading a file, mmProbEd discards comments and moves records it does not understand to the bottom of its output file. Use the FileSource application to serve unmodified problem descriptions.

The menu selection File|Save as... displays a dialog box for selecting/entering a file in which the problem description currently held by mmProbEd is to be saved. Because the internal data format use by mmProbEd is an unordered array that does not include comments (or unrecognized records), the simple operation of reading in a MIF file and then writing it back out may alter the file.

Each instance of mmProbEd contains exactly one problem description at a time. When the option -net 1 is active (the default), each also services requests from client applications (typically solvers) for the problem description it contains.

The main panel in the mmProbEd window contains buttons corresponding to the sections in a MIF 1.1 problem description. Selecting a button brings up another window through which the contents of that section of a problem description may be edited. The MIF sections and the elements they contain are described in detail in the MIF 1.1 documentation. Only one editing window is displayed at a time. The windows may be navigated in order using their Next or Previous buttons.

PLEASE NOTE: The material parameter values provided for the symbolic material types of Iron, Nickel, etc., should not be taken as standard reference values for these materials. These values are only approximate. They are included for convenience, and as examples for users who wish to supply their own material types with symbolic names. To introduce additional material types, edit the file oommf/app/mmpe/materials, appending your new entries in the same format as the example materials.

The menu selection File|Exit terminates the mmProbEd application. The menu Help provides the usual help facilities.
