In this paper we consider the special multilevel algorithm for solving systems of linear algebraic equations obtained by the finite element discretization of the vector Helmholtz equation in the 3D domains with internal borders. The algorithm is based on the multilevel Schwarz method and the domain decomposition with an overlap. The results of calculations allow us to estimate the contribution of the each stage of the algorithm to the acceleration of the calculation procedures.
