The time evolution of magnetic Bur distribution in a 8 x 8 x 8 Josephson-ju
nction network is numerically followed, after the network's lower threshold
field is exceeded. According to results, Josephson network vortices first
form at network edges as bent. With time the vortices straighten and find t
heir stationary positions inside the network. (C) 2000 Elsevier Science B.V
