Outline of Final Research Achievements

The purpose of this study is to develop the simulator for flood disaster to estimate the damage of structure. The interface capturing method for the free surface flow analysis technique based on stabilized finite element method had a local problem on mass conservation of water. This problem was serious to estimate the flooding area. To overcome this problem, we have developed the advection equation solver based on discontinuous Galerkin method.

Academic Significance and Societal Importance of the Research Achievements

水害の被害評価において,氾濫域の予測精度は結果に対し大きな影響を及ぼす.また領域内の水の質量保存が満たされない場合,氾濫域の予測精度は大きく低下することとなる.質量保存を満たすために補正をかける方法も提案されているが,それらは領域全体での質量保存を満たす方法であり,分離や合体を繰り返す氾濫解析では局所的な質量保存が満たされる保証は無い.本研究の成果として開発されたDiscontinuous Galerkin法に基づく方法では,この局所的な質量保存を満たす方法であり,氾濫域の予測精度の向上に大きく寄与する方法である.
