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： .T`%tJ-Em  
Warning: in run: there was no simulation data. The simulation failed to run. /PKNLK  
Error:  Can not find result 'E' in the result provider 'field' ))Za&S*<  
代码如下： #AY&BWS$  
radius = 1e-6*[0.25,0.75]; {P-):  
for (i=1:length(radius)) { /yZcDK4  
    setnamed("::model","radius",radius(i)); ~"A0Rs=  
    run; .e-#

    E = getresult("field","E"); h{qgEIk&  
    x = E.x; 6

    Ex = E.Ex; t_1LL >R
