45. c-inhomogeneities for which with a small number of meshes it is not possible to represent adequately the inhomogeneity distribution. In this case, a small number of meshes could lead to the appearance of important spurious longitudinal and transversal voltages, which are just an artifact of an inadequate simulation. For instance, the calculations of the longitudinal and transversal voltages in superconductors with uniformly distributed inhomogeneities presented by R Griessen and coworkers in Physica C 235-240 1371 (1994) may be affected by these spurious effects.
46. Siebold Th, Carballeira C, Mosqueira J, Ramallo M V and Vidal F 1997 Physica C 282-287 1181. By using three dimensional electrical resistor networks, in this paper it is shown that the presence of non-uniformly distributed inhomogeneities may lead, for some distributions, to the appearance of countercurrents which, when distributed in the sample surface, may lead to negative effective resistivities.
