We use SPH to calculate the gas response in a potential representing a strongly barred galaxy. We examine the dependence of the morphology and of the inflow rate of this response on hydrodynamical and numerical parameters used in the simulations. In particular we study the effects of the sound speed, the rate of growth of the bar and the number of particles used in our models. We also investigate the appropriate value of the artificial viscosity to be used in the models, delimiting a region of values within which the flow is correctly described. We conclude that models with number of particles 104
