Numerical simulation for the 3-D thermoelasticity problem

The paper deals with a numerical model based on the finite element discretization of the 3-D thermoelasticity problem in compound parallelepipedal domain. The piece-wise trilinear functions are used. Iterative process is based on the Neumann-Dirichlet domain decomposition procedure, and numerical experiments demonstrate that the convergence rate does not depend on the grid parameters.
