No.476 SPH要素を用いた土砂崩壊とダム湖への流動挙動解析

例題475の応用版として、SPH要素でモデル化した土砂が崩壊して、ダム湖へ流入する挙動を解析しました。ダム湖の水はSPH要素でモデル化してあります。したがって固体と流体の混相流の解析となっています。

Keywords: SPH elements, Dam-Break, Sediment collapse and flow behavior to dam, sph to sph coupling, debris and water were modeled by sph elements, Multiphase flow

Tool: LS-PrePost ver.4.6, LS-DYNA MPP Single Precision Win64 R11

なお,本事例はサンプルであることをご了承下さい。
