About Sergey

A talented mathematician and specialist in mechanics, senior researcher, head of the sector at the Dorodnitsyn Computing Center, Russian Academy of Sciences, Sergey Alexan­drovich Ivanenko died suddenly on September 24, 2003, as a result of a fatal heart attack. Science lost an outstanding researcher, who left a notable trace in computational fluid dy­namics and numerical mathematics. His entire scientific career was tied with the Computing Center, where he began working as an engineer, then ajunior researcher, and finally became a sector head, where he had many friends, colleagues, and followers. The untimely death of Sergey in the prime of his creative talent has become a great grief for everyone who knew him. A relatively new field in computational mathematics - the theory of curvilinear grid generation - where Sergey was a prominent specialist, also suffered bereavement. Sergey Ivanenko was born on June 11, 1954, in Feodosiya, Crimea. His farther, Alexander Ivanovich Ivanenko, was a chief constructor at the shipbuilding plant, mother, Maria Nikonovna, was a pharmaceutical chemist. In 1971 Sergey graduated from the school in Feodosiya (he was awarded the gold medal for the excellent knowledge) and entered the Department of Control and Applied Mathematics of the Moscow Institute of Physics and Technology. In 1977 he graduated from the Institute and was assigned to the Computing Center, USSR Academy of Sciences. In the first years, his abilities were noted by Academician N.N. Moiseev (1917-2000), who guided many scientific directions at the institution and entrusted various important research studies to Sergey. Sergey focused on developing mathematical methods for modeling dynamics and water quality of inland water basins. He developed several mathematical models and participated in their practical implementation. For practical developing these models he applied the finite element method, a new technique at that time, which later became his specialization along with effective grid generation. Sergey was a leading world specialist in the theory and practice of grid generation.
