Constitutive Matrices Using Hexahedra in a Discrete Approach for Eddy Currents

We examine the construction of reluctivity and Ohm´s constitutive matrices for discrete geometric approaches using nonregular hexahedra as primal volumes. The effect of element deformation on the representation of uniform fields have been investigated for static fields. Then convergence and accuracy of the proposed matrices has been carried out using an eddy-current problem as working example.
