Unformatted text preview: ion two is the air inside and
outside of the sphere which is modeled with the Reduced Scalar Potential formulation using the SOLID96 element.
The two regions are interfaced with the interface element INTER115 at the sphere-air boundary. 1–428 ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. VM189
Flux-parallel boundary conditions are applied at the Φ = 0 and Φ = 20 degree planes. Flux-normal conditions are
applied at the y = 0 plane. At the interface regions, the condition
is enforced by first rotating the nodes
into a spherical coordinate system and then setting the radial component of the vector potential to zero. Electric
flux-normal conditions are enforced at the two circumferential symmetry planes by setting the time-integrated
potential (VOLT) to zero. The external field is applied at the y = .6 m exterior plane by applying a nonzero value
of the scalar potential based on the equation:
B(y) = µ H(y) = - µ grad Φ = - µ ∆ Φ / ∆ y
With this relationship, the scalar potential value at y = .6 m is:
