The threshold for flux-line cutting (intersection and cross-joining of adjacent nonparallel vortices) is considered theoretically for a model array of parallel, equally spaced vortex planes. The vortices within each plane are parallel to each other but are inclined at an angle with respect to vortices in adjacent planes. Forces between vortices are calculated numerically using the interaction force proposed by Brandt, Clem, and Walmsley. Although for small interplanar angles the array is stable, for sufficiently large angles infinitesimal perturbations of the array grow until flux-line cutting occurs.
