FINE_GMAX (.param)

Keyword type



This keyword determines the maximum size of the g-vectors included in the fine grid.

The fine grid is set up such that all g-vectors with |g| less than or equal to FINE_GMAX are included.


-1 a0-1 - this results in the fine and standard grids being identical


FINE_GMAX : 20 1/ang

There is a more convenient way of dealing with fine grid using dimensionless parameter FINE_GRID_SCALE which defines FINE_GMAX in terms of standard grid GMAX.
