Institute of Computational Mathematics and Mathematical Geophysics (Novosibirsk)

In this report is presented general means about complex structured grids, grid data structure macro- and micro- levels, grid data structure transformation algorithms.

Approximation of Poisson equation on these grids is realized with help of final volume method (FVM).The system of linear algebraic equations is solved with help of iteration incomplete factorization method with acceleration conjugate gradients.

Examples of numerical solution of tests and practical tasks are presented.
