We construct self-consistent dynamical models for disk galaxies withtriaxial, cuspy halos. We begin with an equilibrium, axisymmetric,disk-bulge-halo system and apply an artificial acceleration to the haloparticles. By design, this acceleration conserves energy and thereby preservingthe system's differential energy distribution even as its phase spacedistribution function is altered. The halo becomes triaxial but itsspherically-averaged density profile remains largely unchanged. The finalsystem is in equilibrium, to a very good approximation, so long as the halo'sshape changes adiabatically. The disk and bulge are ``live'' while the halo isbeing deformed; they respond to the changing gravitational potential but alsoinfluence the deformation of the halo. We test the hypothesis that halotriaxiality can explain the rotation curves of low surface brightness galaxiesby modelling the galaxy F568-3.
