A hydrodynamic model of FG Sge, the central star of a planetary,nebula, has been reexamined by using the code with rezoning technique. The pulsation period P=29 days is obtained for the model with the parameters, M=1 M_⊙, L=3200 L_⊙ and T_<eff>=5500 K. Stellingwerf's analytical expression is used for the opacities. The calculated amplitude of light variation is 0.45 mag. The growth rate of pulsation is not so great and no strong atmospheric shock waves are found.Stellar pulsationHydrodynamic modelFG Sge
