Abstract :
Some properties of the incomplete gauge A.w=0 formulations for 3-D nodal finite-element magnetostatics are analyzed. Aspects associated with the preconditioning of the Incomplete Cholesky Conjugated Gradients (ICCG) solver, the solution of nonlinear problems and the choice of w are evaluated. A comparison with other magnetic vector potential formulations is also done
