Abstract :
In this paper, an adapted preconditioner and Conjugate Gradient (CG) are presented for the matrix system obtained from the Mortar method applied to the potential formulations. As example of application a magnetostatic problem is studied to validate the reduction of the iterations number for the preconditioned iterative method.
