It is shown that computing time to obtain a converged solution for a typical test problem becomes 1/2 of the computing time of the original pointwise implicit relaxation method., 形態: カラー図版あり, 資料番号: AA0064303006, レポート番号: JAXA-SP-08-009}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {点緩和型陰的Discontinuous Galerkin法の収束加速}, volume = {JAXA-SP-08-009}, year = {2009} }
