[A few questions]




To Dear All:


How are you? I have a few questions.

(1) In the manual, denominator in equation (44) should be r^(n+1). It is obvious mistake, but it did not change from previous manual. The thing I wanted to ask is
How I can use the mixed boundary condition. If I check the axi1.fem file, the c0 coefficient is 6962160. Is this from (1/(mu_0*4.5 inch * 0.0254) ? I would like to make sure that I know correctly. If the problem is the planar in rectangular coordinate, Can I still use same equation (from the center of area of interest to most outside boundary) ?


The thing that I really want to ask is that in the manual it said when n=1, the objects in the solution region look like a dipole when view from a long distance. I would like to more explanation for this.

(2) In the manual, it says resistive losses from i^2*R. I think it should be 0.5*I^2*R. Nevertheless, I think FEMM gives correct value.

(3) In the layout, if I choose entire domain with " define area over which integration performed", and calculate A dot J integration. Should it be same as magnetic field energy ?

Thank you very much.
Sincerely,
SE-HO YOU
