Abstract
We perform two-dimensional, time dependent, hydrodynamical simulations of the gas flow in a potential representing the barred spiral galaxy NGC 1365 using the FS2 code originally written by G.D. van Albada. We find good agreement between observations and models, both concerning the morphology and the velocity field. Contrary to observations, the pure bar perturbed models cannot drive an inner arm across corotation. Models having both a bar and spiral perturbing potential reduce this problem, thus suggesting the existence of massive spiral arms in NGC 1365.
