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： W2`3PEa  
Warning: in run: there was no simulation data. The simulation failed to run. 44 8%yP  
Error:  Can not find result 'E' in the result provider 'field' ~|<'@B!6  
代码如下： &CQ28WG X  
radius = 1e-6*[0.25,0.75]; InL_JobE8r  
for (i=1:length(radius)) {  "O# V/(  
    setnamed("::model","radius",radius(i)); +b_[JP2  
    run; jBEW("4R  
    E = getresult("field","E"); 8@doKOA~T  
    x = E.x; S5gBVGh  
    z = E.z; g'!"klS93  
    Ex = E.Ex; ]*MVC
/R,  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); p/eaO{6 6
