Abstract We employ a set of high-resolution simulations of disk galaxies to argue that dark matter substructures passing through the disk hardly produce transient features in disk, like multi-armed spiral patterns. Indeed, our studies indicate that stochastic spiral arms in galaxies have different origin.
