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： slPFDBx  
Warning: in run: there was no simulation data. The simulation failed to run. WVo%'DtF`  
Error:  Can not find result 'E' in the result provider 'field' r!x^P=f,MJ  
代码如下： D#k>.)g  
radius = 1e-6*[0.25,0.75]; U9N}6a=  
for (i=1:length(radius)) { FlkAo]  
    setnamed("::model","radius",radius(i)); ?Z14l0iZ%d  
    run; _nTjCN625  
    E = getresult("field","E"); +T4<}+n  
    x = E.x; 3cfkJ|fuwe  
    z = E.z; MRJdQCBV  
    Ex = E.Ex; atN`w=6A`  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); >w*"LZjTTK
