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： @O  @|M'  
Warning: in run: there was no simulation data. The simulation failed to run. [)b/uR  
Error:  Can not find result 'E' in the result provider 'field' i9#`F.7F  
代码如下： oHP>v_X  
radius = 1e-6*[0.25,0.75]; D7Rbho<  
for (i=1:length(radius)) { ie$fMBIq  
    setnamed("::model","radius",radius(i)); %k1q4qOG]^  
    run; h0y\,iWXb  
    E = getresult("field","E"); 'vf,T4uQ"

    z = E.z; 6`$,-(J=  
    Ex = E.Ex; skmDsZzw
