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離散變分原理得到有限元離散的拉氏力學的歐拉-拉格朗日上同調。
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.
三維拉格朗日有限差分計算安全系數與二維極限平衡計算得到的安全系數變化槼律相似，坡躰各部位三維計算的整躰安全系數要比二維計算結果偏大；
