Dear Siesta Users, i had try to perform a geometry optimization of some
atoms only, using geometry constrains in Siesta3
I havd try diferent set of parameters to do it, in the GeometryConstraints
section with position -1 to -68 and 1 to 68, but always the geometry
optimization is perform to all the atoms.( The atoms i want to fix are from
1 to 68)
Can anyone help me with this, PLEASE!!!
This is the input file (*.fdf)
Thanks in Advance
Walter
