3D Previews of the LPG cladding mode field

[Felipe Souza]

Hello,
I would like to know about the “3D Preview of the field” in OptiGrating (found at MODE PARAMETERS > VIEW).
It allow us to export a field file *.f3d, which is a txt file. I want to plot the exported field, however, i do not understand the information of the txt file.
Can somebody help me?
Thank you

This text file begins with some data about the size of the window and the number of points in the X axis (NX) and the number in Y (NY). The optical data follows one mesh point at a time as

Z1 complex number z data point with coordinates (xmin, ymin)
Z2 complex number z data point with coordinates (xmin+dx, ymin)
Z3 complex number z data point with coordinates (xmin+2dx, ymin)
ZNX complex number z data point with coordinates (xmax, ymin)
ZNX+1 complex number z data point with coordinates (xmin, ymin+dy)
… …
ZN last complex number z data point with coordinates (xmax, ymax),
N=NXxNY
