We have studied the collisional interaction of disk galaxies using SPH and N-body numerical simulations. We follow the dynamics of a two-component star-gas disk centrifugally balanced by the gravity of a rigid halo. A companion galaxy is modeled self-consistently, and its two-component disk is balanced by the potential of the stellar halo. This model allows us to follow the dynamics of the gas component in the colliding galaxies simultaneously with the dynamics of the collisionless halo of the companion.
