内容記述 | In this paper, a robust method of the unstructured dynamic mesh for three-dimensional moving and deforming body problems is proposed. The method is based on an analogy of both tension and torsion springs for the robustness. The angles of elements that consist of the computational grid and the distance from the body surface are added to the spring coefficient for unstructured dynamic mesh method. The method is applied to some problems to evaluate the robustness and the mesh quality by the comparison with the commonly-used dynamic mesh method based on linear tension spring analogy. It is demonstrated that the proposed method can move the grid very smoothly without generating any invalid tetrahedrons even for problems with large motions. The proposed method extends the application range of the dynamic mesh method for largely moving and deforming body problems. | |||||
