The accurate treatment of own beam space charge influence is the main problem for all beam dynamics codes. Traditionally only the Coulomb field is taking into account for low energy beams and the radiation part is accounting for high energy beams. But now the current of accelerating beam enlarges and some radiation effects should be discussed for low energy beam also. The beam loading is more important of them. This effect should be studied now not only in electron linacs but for proton also. The BAMDULAC code is designing in MEPhI since 1999 for beam dynamics study *. The especial version BEAMDULAC-BL was designed for 3D beam dynamics study with accurate treatment both the Coulomb field and beam loading. The methods of beam loading treatment and the results of code testing are presented in this report. Some examples of beam dynamics study in linacs are discussed.
