      Approximation method for Lame equations on a mesh adapted to a region geometry is presented: boundaries cutting the region into zones with different physical properties run along the mesh cell boundaries. Mesh cells at a x, у-plane are irregular form quadrangles, a mesh along z is specified by a table. Seidel method with multimesh acceleration is suggested for solving difference equations. Convergence iteration data and accuracy analysis for approximate solutions are given.
