静电场，计算完显示电容

计算电容的时候需要提前对模型中的导体定义好节点类型的组件才行。定义好之后再使用2楼的“CMATRIX ”宏命令进行求解。具体的可以参照帮助中的电容计算。

CMATRIX CMATRIX, SYMFAC, Condname, NUMCOND,GRNDKEY, Capname
Performs electrostatic field solutions and calculates the self and mutual capacitances between multiple conductors.





SYMFAC（对称系数）
Geometric symmetry factor. Capacitance values are scaled by this factor which represents the fraction of the total device modeled. Defaults to 1.
Condname（定义的电容组件名称，字符变量）
Alpha-numeric prefix identifier used in defining named conductor components.
NUMCOND（组件总数）
Total Number of Components. If a ground is modeled, it is to be included as a component. If a ground is not modeled, but infinite elements are used to model the far-field ground, a named component for the far-field ground is not required.
GRNDKEY（0代表地也是一个组件，1代表地在无穷远） Ground key:

0	—	Ground is one of the components, which is not at infinity.
1	—	Ground is at infinity (modeled by infinite elements or a Trefftz domain).

Capname Array name for computed capacitance matrix. Defaults to CMATRIX.
