WebA reasonable k-point sampling for many situations is a k-point spacing of 0.05 (in units of 2pi/A). In the cell file, you'd put: kpoint_MP_spacing 0.05 (MP = Monkhorst-Pack) With those... WebThe first three numbers on a line are the co-ordinates of a k-point as fractions of the relevent reciprocal space lattice vector. The final number is a weight for the k-point. The weights of all n k-points must add up to 1. Another way is to use a Monkhurst-Pack grid and there are two ways of doing this.
