I need to calculate group velocity of guided mode (or Group index) in some geometry like line defects. From froum I understood display-group-velocities command in MPB can be useful. But I couldn't find what is output and how can be used? When I extract Group velocities by: grep velocity *.out > result.dat, the output is some vectores like: velocity:, 1, #(0.0 0.0 0.0), #(… velocity:, 2, #(0.546472273423393 0.31550526440082 7.60657916462197e-9), … What do these vectors mean? How can I calculate group velocity of guided mode?
