请问大家下面这段代码中setnamed命令中的几个分别代表什么意思啊？脚本运行的时候发现半径为0.25μm时可以正常运行，但为0.75μm的时候出现一个错误： 3EO:Uk5<  
Warning: in run: there was no simulation data. The simulation failed to run. jWNF3\  
Error:  Can not find result 'E' in the result provider 'field' w6&p4Jw/H?  
代码如下： 9L7jYy=A#  
radius = 1e-6*[0.25,0.75]; P5Is#7udN8  
for (i=1:length(radius)) { 4IGn,D^  
    setnamed("::model","radius",radius(i)); X(M|T]`b:  
    run; _Qd CV`  
    E = getresult("field","E"); YE;Tpji  
    x = E.x; W

    z = E.z; L)yc_ d5  
    Ex = E.Ex; =+ALh-
