ANSYS 3D magnetostatic analyis

ANSYS 3D magnetostatic analyis

ANSYS 3D magnetostatic analyis

(OP)
In a 3D magnetostatic analysis of a volume, including SOURCE36 current source and singly-connected iron regions, I obtain a zero solution. I tried different values of source current and relative magnetic permeability, tried to use or not to use infinite boundary, but result is the same. As prescribed in ANSYS docs I used DSP formulation. What is my mistake?

RE: ANSYS 3D magnetostatic analyis

What is the shape of your part.

RE: ANSYS 3D magnetostatic analyis

(OP)
It's a Hall thruster - cilinder including one coil (internal) around the central magnetic core, surrounding it magnetic screen, a gap, one more magnetic screen, and outside that screen four smaller coils (outer) winded around magnetic cores, aligned with the general cylindrical axis, with an angular gap of 90 degrees. I'm using the cyclic analysis of a quarter (quarter-symmetry) including one of the outer coils.
Thanks in advance
