How to get a more detailed band structure of photonic crystal ?

      Recently I'm learning the calculation of 2D photonic crystal through Lumerical FDTD.

      From this example: https://optics.ansys.com/hc/en-us/articles/360041566614-Rectangular-Photonic-Crystal-Bandstructure, I wanna know how to modify my input data (including the setup script, .lsf file... etc) in order to get a more detailed band structure (ie : 100 different k value instead of 30).

      You can directly modify the sweep number in the sweel utility:

      You will need to modify each of them. the default 10 is for one direction. You can change it to 30, then you can get 90 points since it has 3 directions.
