Just though you all might be interested in some of the latest updates to the computational magnetics links page at http://members.aol.com/_ht_a/gmagnetics/links.htm

Google has recently implemented a very good new translator program which can be incorporated more or less seamlessly into the addresses of foreign language web pages. I've changed the entries for non-English language sites to include an additional link to the translation of the site. Some of the more interesting ones are the Japanese and Korean commercial programs:
http://translate.google.com/translate_c?hl=en&sl=ja&u=http://www.iijnet.or.jp/ELFMAGIC/jp/jp_page.html
http://translate.google.com/translate_c?hl=en&sl=ja&u=http://www.ssil.com/em/EMSolution/EMSol.html
http://translate.google.com/translate_c?hl=en&sl=ko&u=http://www.jat.co.kr/eda/motor/empis.html
http://translate.google.com/translate_c?hl=en&sl=ja&u=http://www.crc.co.jp/science/MAGNA-FIM/magna-fim.htm

Several of the commercial programs have demo versions available that are new, or at least I hadn't noticed before now:

- The Korean program EmFis has a demo version that allows about 5000 nodes and solves 2D/axi magnetostatic and electrostatic problems. An interesting feature is that some VC++ and fortran source code is included with the demo. Although the documentation is in Korean, the program has an intuitive GUI and seems fairly easy to use. See http://www.komotek.com/download/EmFis.zip
- The Japanese program EmSolution is making a demo available as well. You have to fill out a form at http://translate.google.com/translate_c?hl=en&u=http://www.ssil.com/em/EMSolution/ReadMe.html to get the password that you need to download the demo. The demo is all in Japanese and therefore relatively confusing to me. It seems to need Femap as well. If you are interested, there is a node-limited version of Femap that you can download at http://www.femap.com/support/femap/support_downloads.shtml
- Centro Internacional de Métodos Numéricos en Ingeniería at Universitat Politècnica de Catalunya offers a trial version of their program, Emant. http://www.cimne.upc.es/emant/download/default.htm It appears that you apply for a password that unlocks a 1-month license to the program. I think that some people associated with Emant are on the mailing list, so they may have further comments about this demo.
- There is a 14-day full-featured trial version of MI/NASTRAN available at http://www.nastran.com/website/files/analysis/analysis7.htm The makers of this flavor of NASTRAN say that the program does magnetostatics, but I haven't gotten around to checking it out yet--all the files to be downloaded add up to about 14 meg.

The demo version for SLIM has recently gone away. The people working on SLIM tell me that the ftp server where the demo resided went down because Alstom UK, the company that makes SLIM, changed ISP providers. A new dedicated SLIM site is apparently in the works.

Some entries have been added to the Commerical Programs list relatively recently:

- The German program Profi at http://translate.google.com/translate_c?hl=en&sl=de&u=http://www.profi-da.de/psp.htm . This program apparently uses a finite difference formulation, which is sort of unusual for low frequency programs. Papers on the publications page of the site go back to 1986, so this program must have been around a while.
- Flux Expert (http://www.simulog.net/produits/flux1.htm) from the French company Simulog.

If anyone knows of any additional links that might be interesting to include, tell me and I will add them to the list.
