We present simulations of the gas behaviour in the M51 spiral potential, perturbed by the tidal field of NGC5195. These 3D computations are very helpful to interprete the molecular observations (arm-interarm contrast, Z-behaviour, map of velocity dispersion, kinematics, streaming motions) and in particular to guess the pattern speed of the spiral.
