“…LOGOS is a 3D multi-physics code for convective heat and mass transfer, aerodynamic and hydrodynamic simulations on parallel computers [11,[13][14][15][16][17][18]. LOGOS has been successfully verified and demonstrated with sufficiently high efficiency on a number of various hydrodynamic tests, including propagation of gravity waves on a free surface (tsunami) [2,14,18] and industry-specific simulations [11,15]. Speedup of computations on highly parallel computers is provided by an original implementation of the algebraic multigrid method [11,19].…”

“…The described model is implemented in the software package LOGOS, which is used for the numerical simulations presented below. The LOGOS software package has been tested for the given class of problems and has shown sufficiently reliable results [Kozelkov et al, 2013, Kozelkov et al, 2014b, 2015b, 2016b, Volkov et al, 2013, Betelin et al, 2014, Deryugin et al, 2015.…”

“…Изложение основных принципов верификации и валидации методов CFD-моделирования представлены в [1,2]. Процедура валидации, состоящая из стадии оценки сходимости итераций, стадии проверки решения на непротиворечивость, стадии сравнения с экспериментом, а также содержащая уровни классов задач представлена в [1,3].…”
