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： P98X[0&  
Warning: in run: there was no simulation data. The simulation failed to run. _/z)&0DO  
Error:  Can not find result 'E' in the result provider 'field' sJHy=z0m  
代码如下： _A~~L6C  
radius = 1e-6*[0.25,0.75]; ;*37ta  
for (i=1:length(radius)) { g.`t!6Hc  
    setnamed("::model","radius",radius(i)); :}3qZX  
    run; !rsqr32]  
    E = getresult("field","E"); 3>@qQ_8%~  
    x = E.x; 3<UDVt@0  
    z = E.z; faL^=CAe  
    Ex = E.Ex; ;SlS!6.W-  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); u=v%7c2Mx}
