Holman, Heat Transfer, 4th Edition, McGraw-Hill Book Co., Inc., New York, NY, 1976, pg. 104, eqn. 4-14 (analogous field solution). Analysis Type(s): Transient Magnetic Field Analysis (ANTYPE = 4) Element Type(s): 2-D Coupled-Field Solid Elements (PLANE13) Input Listing: vm167.dat Test Case A semi-infinite solid is initially under no external magnetic field (vector potential A is zero throughout). The surface is suddenly subjected to a constant magnetic potential Ao. Determine the eddy current density, flux density and the vector potential field solution in the solid during the transient. Figure 167.1 Semi-Infinite Solid Transient Eddy Currents Problem Sketch Material Properties µ = 4 π x 10-7 H/m ρ = 4 x 10-7 ohm-m Geometric Properties = 20 m h = 0.4 m Loading Ao = 2.0 Wb/m ANSYS Verification Manual .
