Current Source Elements (SOURC36) Input Listing: vm190.dat Test Case
A ferromagnetic core is wound with a 200-turn coil wrapped around one leg. Determine the mmf drop in the
iron core for a coil current of 1 ampere. Figure 190.1 Ferromagnetic Inductor Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–431 VM190

h = 60 cm
L = 55 cm
w = 10 cm
a = 15 cm
b = 30 cm
c = 10 cm Analysis Assumptions and Modeling Notes
Since the core material has finite permeability air is modelled to a small distance away from the core. The open
boundary is modelled with an infinite surface element at the edge of the air region. The model employs 1/4
symmetry (about the Y and Z planes). The current source is modelled by a coil primitive. Dimensions of the coil
are arbitrarily chosen since they have no bearing on the mmf calculations.
The iron core, linked by a coi...
