The theoretical calculations on the most probable mass division in nuclear fission process are given. The model is based on the topographical analysis of the five-dimensional potential energy surface of more than 2.5 million mesh points. Special attention is paid to obtain the energies and deformations of the saddle points without using any approximation. The calculation tells us that there exist multiple saddle points in the static potential energy surface. The lowest and the next lowest saddle point play an important role for the fission process. Of these two saddle points, one is mass-symmetrically deformed and the other is mass-asymmetrically deformed and the relative heights of these two saddle points depend on the fissioning nuclei. In case of Fm isotopes, the relative height of two saddle points appears very sensitively, i.e., $$^{256}$$Fm has asymmetrically deformed lowest saddle point and in $$^{258}$$Fm, the lowest saddle point is symmetrically deformed. This feature explains the phenomenon called bimodal fission.
