CONTROL
Control关键字设置是可选的，可以用于改变默认的求解选项，例如质量缩放，自适
应网格和隐式计算。但是我们建议一定要定义计算终止时间CONTROL_TERMINATION
这一关键字的选项卡。 在K文件中，这些关键字卡片的顺序是任意的。为了避免歧义，
不要定义多个同样类型的关键字卡片。所有的control关键字按照字母排序如下：

LS-DYNA 可以通过两种方式实现隐式计算。首先，使用关键字 *CONTROL _
IMPLICIT _GENERAL 可以实现整个计算模型的隐式计算；此外，还可以利用关键字*
INTERFACE _SPRINGBACK _SEAMLESS在模型显式计算完成后无缝切换到隐式计算。
这一无缝切换的技术主要用于简化金属成型回弹计算（金属成型过程由显式计算完成，
之后立即使用隐式计算完成回弹过程的模拟）。由于切换设置有一定难度，LS-DYNA还
支持利用重启动的方式完成显隐式转换。一共有8种关键字可以用于隐式计算，它们的相
关默认参数已经受到了仔细的调整，以便针对大部分仿真计算都可以实现设置工作的最
小化。总结如下：
*
*
*
CONTROL_IMPLICIT_GENERAL
激活隐式计算，设置时间步长
CONTROL_IMPLICIT_INERTIA_RELIEF
在含有刚性体的模型中使用线性分析
CONTROL_IMPLICIT_SOLVER
设置线性方程的参数[K]{x}={f}
*
*
*
*
CONTROL_IMPLICIT_SOLUTION
设置线性或非线性计算方法，减少误差
CONTROL_IMPLICIT_AUTO
激活时间步自动控制
CONTROL_IMPLICIT_DYNAMICS
激活并设置使用Newmark方法的动态隐式计算
CONTROL_IMPLICIT_EIGENVALUE
激活特征值计算
