Can CST be simulated by code input ?

Hi, all. I'd like to perform a cst simulation by inputting code not through its GUI. Actually, I want to interconnect CST with other opmimization program. For that, I'm designing an interface program. As I know, a code operation is possible in case of PSPICE, but I don't know concerning CST. If somebody knows the way of code operation in CST, please help me. Thank you.
