Unformatted text preview: he applied external field is calculated as B(y) = - δA / δx, so at θ = 0 and r = r∞ , A = -Bor = -.084. The vector potential A varies along r∞ as Aθ = -Bor cos θ. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–368 VM166 The cylinder is assumed to be infinitely long, thus end effects are ignored allowing for a two-dimensional planar analysis. The problem can be modeled in quarter symmetry with the flux-parallel (A = 0) boundary condition at x = 0, and the flux-normal (natural) boundary condition at y = 0. The average power loss in the cylinder is calculated from the real and imaginary power loss density (JHEAT) terms available in the database: n Pavg = ∑ (JHEAT Re + JHEAT lm ) Vi i i i =1 when n is the number of elements in the aluminum cylinder, Vi is the element volume (per-unit-depth). A fine mesh is defined in the cylinder for accurate calculation of the power loss. Results Comparison Target ANSYS Ratio Bx (0,0), T 0 + j0 0 + j0 1.0 By (0,0), T -.00184 -...
