This paper describes how the hybrid FEM-DBCI (Finite Element Method – Dirichlet Boundary Condition Iteration) method can be applied to solve time-harmonic skin effect problems in three-dimensions. The domain of analysis is partitioned into two subdomains: conductors and free space. The conductors are meshed with tetrahedral edge elements and the electrical field is assumed as unknown. The free space is truncated by means of a fictitious boundary and is meshed using tetrahedral nodal elements where the reduced magnetic potential is the scalar unknown. The two domains are treated separately by two FEM analyses, which are applied alternately in an iterative scheme towards convergence.

This paper describes how the hybrid FEM-DBCI (Finite Element Method – Dirichlet Boundary Condition Iteration) method can be applied to solve time-harmonic skin effect problems in three-dimensions. The domain of analysis is partitioned into two subdomains: conductors and free space. The conductors are meshed with tetrahedral edge elements and the electrical field is assumed as unknown. The free space is truncated by means of a fictitious boundary and is meshed using tetrahedral nodal elements where the reduced magnetic potential is the scalar unknown. The two domains are treated separately by two FEM analyses, which are applied alternately in an iterative scheme towards convergence.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
