lagrangian finite-difference

基本解释

Besides, Chapter Three gets the Euler-Lagrange cohomology in the finite element discrete Lagrangian mechanics via the difference discrete variational principle.
此外，文中第三部分用差分离散变分原理得到有限元离散的拉氏力学的欧拉-拉格朗日上同调。
The differences of safety factor between the two methods are similar, but the safety factor by Lagrangian finite difference is larger than that of Two-dimensional limit equilibrium.
三维拉格朗日有限差分计算安全系数与二维极限平衡计算得到的安全系数变化规律相似，坡体各部位三维计算的整体安全系数要比二维计算结果偏大；
