PROGRAM REALIZATION OF DISCRETE MATHEMATICAL MODEL OF COASTAL WAVE PROCESSES CALCULATION BASED ON EXPLICIT SCHEMES REGULARIZED BY B.N. CHETVERTUSHKIN IS PERFORMED ON COMPUTING SYSTEM WITH MASSIVE PARALLELISM
Continuous mathematical model of calculation of wave exit to the shore and its destruction taking into account such physical parameters as turbulent exchange, complex geometry of the bottom and the coastline, bottom friction is under consideration. An effective algorithm of its realization taking into account a dynamic level change of liquid elevation is constructed. The method of construction of grids with dynamically changing geometry of rated operating conditions is developed. The algorithm of problem solving of diffusion convection on the basis of the explicit regularized schemes is constructed and its parallel realization is performed. Program complex intended for the visualization of two-dimensional velocity field of aquatic environment movement in case of mathematical modeling of wave setup and its breaking-down to the shore, as well as for wave processes forecasting in offshore strip is developed, on the basis of which the fields of aquatic environment course consistent with real physical process is derived.
