The TIM technique solves time-dependent 3D continuum mechanics problems using arbitrarily structured non-regular polyhedral Lagrangian grids. The authors faced the problem of the format implementation to describe the grid structure at developing the technique foundation. The storage format should be economical enough, that is it requires the minimum main memory capacity and satisfies the implementation of the counting algorithms of the technique. Three universal formats have been investigated, and “bound-by-bound” storage structure has been chosen for the TIM technique: bound list is stored for the cell, a pair of cells and node list are stored for the bound, the number of one of the bounds is stored for the node.
