有没有人用过CST MWS近场源的“nfd”文件

下面的代码就是cst中提供的nfd文件的例子，我想照着它改成适合自己模型的场源，我需要一个频率为3Khz的时域波形作为场源。修改频率为3000、1500，尺寸放大10^6倍，场数据不变，结果总是报错

不知道是哪些指标不合格，求教高人指点！这阵子就研究这个，焦头烂额的说，求大神帮助！
！ Any line starting with ！ is treated as a comment line.
！ All dimensions are in (meters, Hz, V/m, A/m).
！ All field values are peak values of a time-harmonic signal.
！
！ A single file can contain several frequency point data over a rectangular box (six surfaces).
！
！ Samples are uniformly spaced in x-, y-, and z-directions, respectively.
！ Tangential E and H fields are available on each surface.
！
！ Let (i,j,k) be the indices along x-, y- and z-directions, respectively.
！ 1 <= i <= Nx;  1<= j <= Ny; 1 <= k <= Nz
！
！ For example, the Z = constant surface has x and y as tangential components.
！              Each data line on this surface has "Exr Exi Eyr Eyi Hxr Hxi Hyr Hyi" (a total of 8 double precision values).
！              For each x (fixed i), the y-coordinate (j) is varied and the fields at the center of the cell are written on one line.            
！           x = Xmin - dx/2 + i*dx
！              y = Ymin - dy/2 + j*dy
