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： wT.V3G  
Warning: in run: there was no simulation data. The simulation failed to run.  |u$AzI  
Error:  Can not find result 'E' in the result provider 'field' -rH3rKtf~  
代码如下： {yG)Ii  
radius = 1e-6*[0.25,0.75]; &.4lhfI+(Q  
for (i=1:length(radius)) { L>@6lhD)x  
    setnamed("::model","radius",radius(i)); -Xd/-,zPY  
    run; qKSM*k~  
    E = getresult("field","E"); x b_C1n  
    x = E.x; 2"i<--Y  
    z = E.z; )8Q|y  
    Ex = E.Ex; W)9KYI9u  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); FlkAo]
