由于所得到的运动方程的非线性和大量的自由度，经受大变形的结构的有限元模拟可能意味着长的模拟时间。特别是对于设计研究，运动方程必须多次求解，因此非常希望减少模拟时间。
Finite element simulations of structures that undergo large deformations can imply long simulation times due to the nonlinearity of the resulting equations of motion and a high number of degrees of freedom. Especially for design studies, where the equations of motion must be solved several times, it is highly desired to reduce the simulation time.
