Damian and Aurelien,
Thank you very much for the kind reply! It is helpful, but still there is much work in the post processing, especially when I’m not very familiar with the Matlab. And it is difficult for me the show the total E in the colored strip format like what is shown in the reference. It will be better if the f3d file can show the total E in one file rather than Ex, Ey, Ez in three separate files.
