Example of meshing using tetrahedral elements. (a) Zoom of the only quadrant considered in the three-dimensional model of the Fig. 1b. (b) Meshing using tetrahedral elements. The mesh size is smaller where the gradient of electric field and current density are maximum, i.e. where the heating occurs. The optimum value of this parameter is calculated by convergence tests.
