A barred galaxy is mainly built of billions of stars moving on different orbits. Understanding of the orbital structure is essential for the interpretation of observations. The orbital structure can be investigated using analytical models and N-body simulations. This paper presents a method to classify orbits found in N-body simulations, i.e. orbits in a time-dependent potential. I present some results about mass loss and mass gain of bars and the influence of a bulge.
