Finite Superelement Method for the solution of the 3d elasticity problems.The numerical investigation

M. P. Galanin, S. A. Lazareva, E. B. Savenkov

Abstract: The results of numerical investigation of Finite Superelement Method (FSEM) for the solution of the 3d elasticity problems are given. Different variants of FSEM are being considered, and their comparative analysis is being carried out. The variants are based on the finite element interpolation techniques on a superelements boundaries. FSEM and FEM efficiency comparison is presented for the model problem. Quantity error data are obtained. When choosing the correct way of constructing and realization the FSEM calculation scheme, the investigated method is of high efficiency.
