Help? Want to see the magnetic field between magnets

Hi guys,

I want to see the magetic field distribution between two cylinder magnet posts.

I first tried to use Maxwell 3D (never used before, just knew it works for field issues) to see the field. I chose two simo24 magnets, and then tried to analyze. However, maxwell gave the error as following:

[error] There are multiple disconnected solution domains. This is not allowed in magnetostatics. (3:12 PM Nov 05, 2009)


Then, I tried to use CST (barelly used before, heard of that it works for physics issues). However, I cannot even find any magnet materials, no simo at all.

Could any friend here help me regarding there issues?

Thanks.

Does anyone know about this?

just an idea.
you have to put them in a box.calculation box.i mean a volume that program will solve the problem.
