In the context of 2-D and 3-D unstructured mixed-element meshes, a new method of recovering vectorial fields and currents in multidimensional simulation is introduced. The new method, called the method of edge elements, directly interpolates the projections of the vectors on the edges of an element into its interior. The new method is compared to two other recovery methods on the basis of resolution, consistency, and implementation ease.
