CST MWS近场源的“nfd”文件，有没有人用过

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！

! Samples are uniformly spaced in x-, y-, and z-directions, respectively.
! Tangential E and H fields are available on each surface.

!
! 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.
