Bulk currents (BC) could be made of elements which contain more than one interval. There are two possibilities:
direction is explictly defined. In that case, the intervals may consist on surfaces, lines, or points, bulk currents are defined as planes in the dual grid containing those entities.direction is not explicitly defined. In that case intervals can only be surfaces.
The sign of surfaces is preserved. BC computes the field circulation on the contour on each surfaces, accounting for the sign.The integrals are added to obtain a single value of BC per probe.
For instance if two intervals, occupy the same space with opposite directions, the BC is always zero.
