Abstract
The authors report numerical simulations of classical vortex motion in two-dimensional arrays of under-damped Josephson junctions. A very efficient algorithm was developed, using a piecewise linear approximation for the Josephson current. They find no indication for ballistic motion, in square arrays nor in triangular arrays. Instead, in the limit of very low damping, there appears to be an effective viscosity due to excitation of the lattice behind the moving vortex
