Development of a simulator allowing to calculate contact interaction of solids on irregular polyhedral Lagrangian grids in three-dimensional approximation is considered in the paper. Contact boundary of solids is described with the help of triangulated surface obtained by triangulation of solids surfaces used in TIM technique calculations. Specially developed algorithms are used to form and keep this surface. Algorithm of inelastic collision is posited in calculation algorithm for interaction of two triangular surfaces. The results of test calculations showing efficiency of calculation technique for contact boundary movement on methodical and test problems are presented. The developed algorithm for calculation of contact boundary movement allows to expand the class of simulated problems in 3D-statement in TIM technique.
