• Keyword descriptions

  ANNEALING
  	ANNEALING {Real}
  	Specify the annealing coefficient
  	This keyword cannot be repeated and it expects precisely one real.
  	Default value: 1.00000000E+000

  PROJ_VELOCITY_VERLET
  	PROJ_VELOCITY_VERLET {Logical}
  	Uses a Projected Velocity Verlet instead of a normal Velocity Verlet. Every time the cosine between velocities and forces is < 0 velocities are zeroed.
  	This keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .TRUE.

  SD_LIKE
  	SD_LIKE {Logical}
  	Zeros velocity at each MD step emulating a steepest descent like(SD_LIKE) approach
  	This keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.
