A parallel computation method for interfaces for solving 3D non- stationary problems of continuum mechanics in Lagrangian variables on regular grids in the frames of the D technique is discussed. The method is destined for computation of contact interactions between mathematical domains with noncoincident computational grids. It allows computation of serious tangential gaps, objects’ collisions, separation of thin shells under the impact of rarefaction waves. The method supports problem computation in both gas-dynamics and elastic-plastic approximation. The essence of the considered method is presented in the paper, general parallelization organization is discussed. A number of model problems is presented.
