CST有没有TUNING的功能？

有。请善用软件的帮助文件。
CST MWS帮助文件《Table Properties》。
Tune: Choose this mode if you want to visualize the influence of different parameters to the result. Therefore, only one result curve is plotted at one time. In the table below, all parameters are listed by their Parameter names together with their Selected values. These fixed values can be changed either by selecting a new value from the corresponding drop-down list or by moving the Tune slider.
