source current density

[aldone]

I am doing a analisys magnetic field 2d and i am using source current density (JS) as excitation dloads.. In example vm165 the current density is applied by command BFA above area...In other example the current density is applied by command BFE hence all element of area. The question are:
1) What correct command do i use for current density BFA or BFE?
2)If i use BFE the correct value of current density (JS) is same of BFA command or is ncessary to divide the total current density on total nunber of element?
Tanks and best regards.
N.B:exuse me for no correct english

Hello aklone,
i think the ways in which you apply the current density are similar, because solid model loads applied by bfa are transferred to the mesh during solution.

And the current density for the area and the elements are the same if you apply them to all elements of the area.

Best regards
