The workshop opened with a pre-session presentation by Mike Donahue and Don Porter describing and demonstrating the capabilities of the OOMMF public code. This package has been ported to a large number of operating systems and while it has been designed to allow programmers to write and substitute modules, programming skills are not required to use the package with its large number of options. The OOMMF distribution is currently limited to 2-D arrays of spins, but 3-D arrays are planned for future releases.
Bob McMichael presented solutions using a 2D square grid using different magnetostatic field algorithms. Constant magnetization methods and constant charge methods give very similar results when extrapolated to zero cell size, but without edge corrections, the constant charge method gives results that depend more strongly on cell size. Results taken over the range 3 < d/lex < 75 show different reversal mechanisms for d/lex < 30, including reversal initiated by switching of the end domains and vortex formation in the end domains.
Thomas Schrefl presented Problem #2 solutions calculated using a finite element method, comparing results obtained with the field directed along the  direction (as in the problem specification) with results obtained with the field along the  direction. Vortex formation is suppressed for fields along , giving a weak dependence of Hc on the particle size up to d/lex = 30. In contrast, for fields along , vortices form, and Hc drops for particle sizes greater than d/lex = 20.
The session concluded with two transparencies comparing data from the three Problem #2 solutions. The close agreement between these solutions received an enthusiastic round of applause.
