Analysis Type(s): Full Harmonic Response Analysis (ANTYPE = 3) Element Type(s): 3-D Magnetic Solid Elements (SOLID97) 3-D Magnetic Scalar Solid Elements (SOLID96) 3-D Magnetic Interface Elements (INTER115) Input Listing: vm189.dat Test Case A hollow aluminum sphere is subjected to a uniform sinusoidally varying magnetic field. Determine the peak flux density at the center of the sphere and the average power loss within the sphere. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–427 VM189 Figure 189.1 Hollow Sphere Problem Sketch Material Properties µr = 1 (aluminum) ρ = 2 x 10-9 ohm-m Geometric Properties ri = .05 m ro = .055 m Loading B = B(y) = Bocos ωt Bo = 1 T ω = 50 Hz Analysis Assumptions and Modeling Notes The problem is symmetric such that an arbitrary circumferential slice (Φ-direction) can be chosen along with a half-symmetry slice about the Y axis. A circumferential slice of Φ = 20 degrees is arbitrarily selected. A rectangular exterior boundary is located at a distance of 0.6 m where the external field load is applied. To maximize efficiency, the model is divided into two regions. Region 1 is the hollow aluminum sphere which is modeled with the vector potential formulation using the SOLID97 element. Reg...
