muMAG Action Plan
muMAG Action Plan
In response to the issues raised at the April 1995 workshop, the muMAG
steering committee is working towards formation of two working groups
which are described below, one on standard problems and verification
and one on portable public micromagnetic code. In addition, to aid
information exchange and formation of other collaborative efforts,
people with an interest in micromagnetics are encouraged to subscribe to one or more of our
I. Standard Problems and Verification Working Group
The function of this group will be to devise standard micromagnetic problems
for the purpose of checking micromagnetic code, i.e. for comparisons of
accuracy and speed of computational techniques. The anticipated tasks of this
working group will include
The group will consider the "team problem" approach for this work. A parallel
experimental program is anticipated which will fabricate real samples
corresponding to the standard problems, for experimental verification of
- selection of standard problems with experimentally accessible material
parameters and applied fields,
- calculation of benchmark solutions to the standard problems,
- evaluation of various computational techniques for speed and accuracy.
Specifications for Standard Problem #1 are here.
II. Portable Public Code Working Group
The function of this group will be to devise and implement a scheme for
publicly accessible micromagnetic code with modules for problem description,
solution, and analysis. The anticipated tasks for this working group include
Additional issues including questions of support for the code (who, if anyone,
will answer questions and help beginners) and questions of motivation for
researchers to release privately developed code must also be addressed.
- formulation of standard data formats for portability,
- specification of module interfaces and functionality to allow the code to
be improved by module replacement.
Researchers interested in participation in either of these working groups are encouraged
to contact Bob McMichael for further information.
