Variational methods of 2D grids calculating for nonstationary problems.
Abstract:
Universal variantional functionals are supposed to be used for calculation of 2D grids in nonstationary problems of mathematical physics with moving boundaries. Their coefficients are determinated by grid metric parameters calculated on previous time step and corrected additionally by others variantional functionals with weighted coefficients proportionally to time step. Discretization of functionals and iterative methods of solving of obtained system are under consideration.
