LMIXTAU = .TRUE. | .FALSE.
Default: LMIXTAU = .FALSE.

Description: send the kinetic-energy density through the density mixer as well.

In many cases, the density-mixing scheme works well enough without passing the kinetic-energy density through the mixer. Therefore VASP uses LMIXTAU=.FALSE. per default. However, when the self-consistency cycle fails to converge for one of the algorithms exploiting density mixing, e.g, IALGO=38 or 48, we recommend setting LMIXTAU=.TRUE..
