To study the effects of space charge in cyclotrons and synchrocyclotrons the code PHASCOL is developed. A method of large (macro)particles is realized in this code. The complete equations of motion of the charged particle in electromagnetic field of accelerator are integrated taking into account the three-dimensional self-electric field of beam. Two methods were used for the calculation of the beam field: the particle-to-particle method and the particle-in-cell one. The results of calculations which illustrate space-charge effects on the parameters of beam in the process of acceleration are given. Both methods have shown a similar influence of space charge on the beam.
