It requires the version 5.3.1.348 and won't be useful even for 5.3 version.

Dear Dr. Elabbasi,

I have a question regarding the computation of a phononic structure, I am trying to compute a band diagram of a phononic crystal but I would like to span four edges of the irreducible Brillouin zone (IBZ), not only 3 edges as in the tutorial file, and eventually to have my band diagram computed for a Bloch wavenumber spanning from Γ(0,0) to X(pi/L,0) to M(pi/L,pi/L) to Y (0,pi/L) and then back to Γ. Can you give me clues or ideas of what I should do to add a 4th segment on my band diagram going from Y to Γ? So far, I can only span 3 segments so my wavenumber goes from Γ(0,0) to X(pi/L,0) to M(pi/L,pi/L) to Y (0,pi/L). But I miss the segment from Y (0,pi/L) to Γ(0,0).

Thank You.

Best regards,
Bogdan

In this example can you please explain kx ky wave vectors. How you write these vectors??

Thank you.
