I can't seem to increase the length of the vectors, even if I multiply the vectors by 1000! Using Mathematica 6.0.2.0. Example: VectorFieldPlot3D[ 1000*nrmDblSinClamp[x, y, boxXext, boxYext, 2, 1, 0.0, 20.0], {x, boxXext[[1]], boxXext[[2]]}, {y, boxYext[[1]], boxYext[[2]]}, {z, -2, 2}, Axes -> True, AxesLabel -> {X, Y, Z}, VectorHeads -> True]
