full mesh=(y or n):

N.B.:
Generate n1 x n2 x n3 Monkhorst-Pack grids. The grid offsets sk1, sk2, sk3 must be 0 ( no offset ) or 1 ( grid displaced by half a grid step in the corresponding direction ).
The result is used as k-points in unit of 2π/alat. alat=celldm(1). bravais can not be 0.

Bravais not set or =0.
