The classical energy functional of complete IBM-1 model version is studied in terms of nuclear shape variables (β, γ), employing two essential control parameters (r2, r1) used in catastrophe theory formalism. The dependence of energy surface equilibrium values from deformation parameter β is analyzed in the case when β = 0. The results, obtained for critical points and phase transition lines between spherical (β = 0) and two deformed (β > 0, β < 0) shapes, are compared with the ones, following from the studies, in which the simplified extended Casten triangle version of interacting boson model was used.
