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： D}

Warning: in run: there was no simulation data. The simulation failed to run. Ct)58f2  
Error:  Can not find result 'E' in the result provider 'field' i;^lh]u  
代码如下： zb9G&'7  
radius = 1e-6*[0.25,0.75]; R

for (i=1:length(radius)) { .yy*[56X  
    setnamed("::model","radius",radius(i)); =fRS UtX  
    run; T

    E = getresult("field","E"); !lNyoX/  
    x = E.x; c<|y/n  
    z = E.z; 68u?}8}  
    Ex = E.Ex; X|{Tljn
