Повышение быстродействия диагностической метеорологической модели системы РОДОС

Abstract

Methods of optimizing the numerical solution of Poisson equation in mass-conservative diagnostic wind flow model are compared. Line relaxation method performs well only with large values of anisotropy parameter and closed upper boundary. Preconditioned conjugate gradient methods perform well in all conditions, with MILU preconditioner on average 2 times better than ILU.
