Construction technique for an irregular three-dimensional grid on the basis of a two-dimensional regular quadrangular grid or an irregular multangular grid is described. Construction of a two-dimensional grid is realized by partitioning of domains into subdomains, filling of each domain by a grid, overlapping of transformations and joining of subdomains into one countable domain. Construction of a three-dimensional grid is carried out per sheet by relocating of a two-dimensional grid along a specified vector in space or by its turning around a specified axis. Both the initial two-dimensional grid and the grid obtained after calculating of initial movement stage using two-dimensional technique may serve as an initial grid. Both techniques allow to construct grids for several countable domains.
