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： Sd2R$r  
Warning: in run: there was no simulation data. The simulation failed to run. yb2*K+Kv  
Error:  Can not find result 'E' in the result provider 'field' VjS %!P  
代码如下： s<cg&`u,<M  
radius = 1e-6*[0.25,0.75]; !u.{<51b  
for (i=1:length(radius)) { Hv>A$x$q  
    setnamed("::model","radius",radius(i)); hV;Tm7I2  
    run; "!i7U2M'  
    E = getresult("field","E"); p#HPWW"  
    x = E.x; pv+FP
B  
    z = E.z; <T[%03  
    Ex = E.Ex; 5YUn{qtD  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); f&bY=$iff  
    switchtolayout; j01.`G7Q  
}
