Therefore they have a great degree of flexibility in dealing with the complex motion of surfaces or boundaries. In this study, novel particle methods are developed as discrete Hamiltonian systems which approximate the infinite dimensional Hamiltonian systems for incompressible fluid flows and nonlinear elastodynamics. Some numerical tests indicate the excellence of these methods in conservation of mechanical energy as well as linear and angular momenta., 形態: カラー図版あり, 資料番号: AA0064237025, レポート番号: JAXA-SP-08-006}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {粒子法とその高精度化への試みについて}, volume = {JAXA-SP-08-006}, year = {2009} }
