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： 0eQ5LG?)  
Warning: in run: there was no simulation data. The simulation failed to run. uN$X3Ls_  
Error:  Can not find result 'E' in the result provider 'field' <[~x]-  
代码如下： 3N]pN<3@  
radius = 1e-6*[0.25,0.75]; t4gD*j6J3  
for (i=1:length(radius)) { !5A nr  
    setnamed("::model","radius",radius(i)); vjXvjv{t  
    run; k ,<L#?,a  
    E = getresult("field","E"); (Mtc&+n{  
    x = E.x; ~Zj?%4
 
    z = E.z; -CL
7^  
    Ex = E.Ex; d9Q%GG0]  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); 2&tGJq-E
