HI, Prof. Steven,
Thanks for your kind reply. I will try to do it by Scheme file I/O after
reading something about it online. About the number of points, that's because I
need the field components on the surfaces of Photonic crystal including fields
on the holes' surfaces which are not flat. And the positions are not always
those of the FDTD lattice nodes. Although it can be done by interpolation with
those volume data from MEEP, the size of the files is big. MEEP can output
fields at any point, and the file can be smaller if only the needed data is
output with externally generated files with (x,y,z). I haven't think of any
other methods currently.
Thanks.
Best,
Jiangjun
