BOUNDARY ELEMENT ANALYSIS METHOD FOR 3-D TRANSIENT EDDY-CURRENT PROBLEMS BASED ON THE 2ND-ORDER VECTOR POTENTIAL FORMULATION

This paper deals with the Boundary Element Analysis Method for 3-D transient eddy current problems formulated in terms of the Vector Potential (SOVP). Indirect boundary in equations are derived using time-dependent fundamental solution and the fictitious sources densities. In numerical implementation, a time stepping convolution approach is adopted to eliminate the need for volume discretization and domain integration. Numerical results of a benchmark problem are provided to demonstrate the validity and accuracy of the technique.
