Tcl and Tk must be installed before installing OOMMF. Tcl and Tk are available for free download from Scriptics Corporation. We recommend the latest stable versions of Tcl and Tk concurrent with this release of OOMMF. OOMMF requires at least Tcl version 7.5 and Tk version 4.1 on Unix platforms, and requires at least Tcl version 7.6 and Tk version 4.2 on Microsoft Windows platforms. OOMMF software does not support any alpha or beta versions 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.
A Tcl/Tk installation includes two shell programs. The names of these programs may vary depending on the Tcl/Tk version and the type of platform. The first shell program contains an interpreter for the base Tcl language. In the OOMMF documentation we refer to this program as tclsh. The second shell program contains an interpreter for the base Tcl language extended by the Tcl commands supplied by the Tk toolkit. In the OOMMF documentation we refer to this program as wish. Consult your Tcl/Tk documentation to determine the actual names of these programs on your platform (for example, tclsh80.exe or wish4.2).
OOMMF applications communicate via TCP/IP network sockets. This means that OOMMF requires support for networking, even on a stand-alone machine. At a minimum, OOMMF must be able to access the loopback interface so that the host can talk to itself using TCP/IP.
The OOMMF source distribution unpacks into a directory tree containing about 400 files and directories, occupying between 5 and 6 MB of storage. Compiling and linking for each platform consumes approximately an additional 5 MB of storage. The OOMMF distribution containing Windows executables unpacks into a directory tree occupying about 8 MB of storage. Note: On a non-compressed FAT16 file system on a large disk, OOMMF may take up much more disk space. This is because on such systems, the minimum size of any file is large, as much as 32 KB. Since this is much larger than many files in the OOMMF distribution require, a great deal of disk space is wasted.
To build OOMMF software from source code, you will need a C++ compiler capable of handling C++ templates, as well as other software development utilities for your platform. We do development and test builds on the following platforms, although porting to others should not be difficult:
