I need three sources of shareware (under $100 license fee) for magnet modeling 
for speaker magnets. It must include NeFeB magents. Can you get me three to 
review?

Dear jhs,

Hello and thank you for your inquiry!

It appears that today this type of software available is generally much more 
than $100.  What seems to be available are stripped down or trial versions, 
which may or may not meet your criteria and needs.  In addition to the 
Quickfield software referenced in the Comment below, the most promising find is 
probably from Autofea.  You can download a free trail of software from Autofea, 
it might be sufficient if your problem can be formulated in less than 300 nodes.

PDE Solutions also has some free software you can download to try:
FlexPDE finite element model builder for Partial Differential Equations:

With more specific information, you might be able piece together your own 
package using programs from the following websites:

Quickfield (http://www.quickfield.com/) is a software package for simulating 
fields, including magnetic fields for speakers.  However, it's impossible to 
tell how much they charge for the professional version - they will only give 
you a quote if you submit some fairly detailed information about yourself and 
your company.  (They do have a free student version which may not be accurate 
enough for your needs).

Hi,

Why dont you try the EDA package EDWin XP/2000, they have a special
summer sale at giveaway prices. I like this software much more than
Protel.
