The simulation based on mesh can be divided into two descriptions: the Eulerian description and the Lagrangiandescription.
基于网格的方法可以分为两种描述：欧拉描述法和拉格朗日描述法。

The material points are followed throughout the deformation of a solid and provide a Lagrangiandescription that is not subject to mesh tangling.
物质点的运动表示了固体变形的全过程并用拉格郎日观点描述。
3
Based on the updated Lagrangiandescription, the incremental equilibrium equations of triangular plate shell elements for geometrically nonlinear problem are derived.
