Description technique of relations between Euler's grid and Lagrange objects
An algorithm with an asymptotic behaviour in the process of data structures creation and its maintenance in an active state is proposed for the description of connections between Euler grid and Lagrange particles. The motion of rigid particles in a gaseous media in the ``least favorable'' case is considered as the test example. Under the least favorable case it is understood: the Lagrange coordinates of particles are not ordered in the space and both a relation of the particle relaxation time to the integration step and a relation of the particle mass to the gas mass can be of an arbitrary value.
