MAXDIS = [real] 

Default: MAXDIS = 0.0 (switched off)

Description: This tag sets the maximum distance that an atom is allowed to travel (in Angstrom) between two ab-initio steps before the charge density is reset to atomic an atomic charge density.


At each ionic step, the maximum Cartesian displacement of any atom (using minimum-image convention) is compared to MAXDIS. If exceeded, the charge density extrapolation controlled by IWAVPR is skipped and atomic densities are used instead. Setting MAXDIS=0.0 disables this reset entirely.
