As there was a few questions recently regarding magnet modeling I hope attachment could help people interesting in this area. This approach I have found at other fem site. I did not try to model it with David's program but acc. to pg. 56 you should be able to simulate coercive force. At the end I would like to introduce myself to the Group. My expertise is in design of large power transformers. For more than 10 years I am using FEM software's in electrostatic problems. In last 3 years I am using FEM in simulating leakage field and estimation of hot spot temperatures in transformer core frames and other structural parts. Recently I have done simulation of 220 MVA, auto transformer with in-house software and with David program. I did get very encouraging results with femm3.0. I could not have believe that I can now have program like this for free and my company spend quit a few millions to develop in-house software. Additionally you certainly have the best site to discuss about magnetics. Many thanks to David and best regards to all. Stephan.
