Yes, your choices are very good. Other than OPERA I have tried or actually leased all of them. I hesitated with OPERA because I am a machine designer and they have not paid as much attention to machines. The others provide varying degrees of assistance to us "old time" motor designers..Ansoft trying the hardest lately with an analytical front end. Each has isses, mostly commercial / support / ease of use. In fact, the easiest to use was IES but the answers were inconsistent from model to model and did not agree with finite element. I could not recommend one over the other. I would say the solvers are all robust. I could go on. Anyway, I'm glad you were amused. Dave, I don't know if you get enough praise and thanks for your work. It would be, is, great to have an open source finite element program available. It would also be nice if it were to develop like a "Netscape" and the magnetics community could improve and expand it. But alas that is not an easy task. I only wish I could contribute more but my expertise in the theory and math is limited. Anyway thanks for your time, work, and creativity. Best of luck in 2001. ----- Original Message ----- From: C.Prem Kumar To: femm@egroups.com ; Dave Squires Sent: Thursday, January 04, 2001 2:57 AM Subject: [femm] Re: FE magnetics commercial ware Hello Dave & Steven, I've been tracking the conversation as a femm-member. These last two communications really left me amused ! May be, I should share information with you at this point regarding other commercial FE-Magnetics software that you would like to evaluate sometime or the other - ONE : Software Name : MAXWELL 2D/3D Magnetic Field Simulator Solvers : Electrostatic, Non-linear Magnetostatic, Non-linear Eddy Current, Parametric capability Web site : www.ansoft.com e-mail : info@ansoft.com TWO : Software Name : OPERA - 2D/3D, TOSCA, ELECTRA, CARMEN- 3D Solvers : All as detailed earlier Web site : www.vectorfields.com e-mail : info@vectorfields.com THREE : Software Name : Magnet 6 Solvers : as before Web site :www.infolytica.com e-mail : info@infolytica.com FOUR : Software Name : Flux-2D, Flux-3D, Phi-3D, Flux_Param, Atila etc.... Web site : www.magsoft.flux.com e-mail : info@magsoft.flux.com Thank you Prem Kumar Dave Squires wrote: `Steven,` `I am evaluating Amperes right now.
