$addefmassxyz is the command to input effective mass along different directions and considering the valley number. The format is Z is the growth direction.
$addefmassxyz type mhh_z mhh_x mhh_y N_valley mlh_z mlh_x mlh_y N_valley me_z me_x me_y N_valley me2_z me2_x me2_y N_valley
If type = 1, the 2nd electron valley is not considered. For example, For Si in the bulk condition with 6 valleys
$addefmassxyz 1 0.45 0.45 0.45 1 0.87 0.87 0.87 1 0.19 0.19 0.98 6 1 0.45 0.45 0.45 1 0.87 0.87 0.87 1 0.19 0.19 0.98 6 1 0.45 0.45 0.45 1 0.87 0.87 0.87 1 0.19 0.19 0.98 6
For GaAs material with 2nd valley has 3 valley in the X valley
