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： _%Ua8bR$  
Warning: in run: there was no simulation data. The simulation failed to run. aJtpaW@  
Error:  Can not find result 'E' in the result provider 'field' S("dU`T?  
代码如下： bBXLW}W  
radius = 1e-6*[0.25,0.75]; &['x+vL9  
for (i=1:length(radius)) { "wg$ H1K  
    setnamed("::model","radius",radius(i)); h^qZi@L  
    run; %l#X6jkt  
    E = getresult("field","E"); [~

    z = E.z; &zJ\D`\,O  
    Ex = E.Ex; NI.ROk1{+4
