We calculate numerically the behavior of a model high-temperaure superconductor described by a three-dimensional array of Josephson junctions in the presence of an external magnetic field using dynamical Langevin simulations in the extreme type-II case. In particular, the voltage generated when an external current is applied, and its dependence on the external field and thickness of the sample are discussed. We find that the ab-plane resistivity is well described by a thermal activation model, whereas the c-axis resistivity appears for higher temperatures. To make connection with recent experiments, the response to nonhomogeneous applied currents is also discussed.
