Molecular dynamics simulation of the dependency dust plasma cluster structure on confinement field anisotropy was carried out. The interaction between dust particles was described on the base of Debye-Huckel potential. The results showed that confinement field anisotropy greatly affects shape and structure of dust plasma clusters. The single-component dust plasma cluster represented a Coulomb ball with a typical shell structure in the ground state in the spherically symmetric confinement field. The simulated system tended to the transition from a bulk to plane shape at the decrease of the horizontal confinement field component to compare with vertical one. At the same time the simulated system tended to the transition from the plane to bulk shape and formation of the shell structure in the ground state at the increase of the dust particle number.
