[Pw_forum] Regarding controlled dynamics

[Vipul Shivaji Ghemud]

Hi all,
I am planing to work on interfaces. In doing so, I want to keep few layers
of a structure fixed while few to relax. In short this is what I am
planning :

10A vacuum
2layers fixed
4layers to relax
2layers fixed

How can I do this type of controlled dynamics?

Thanx in advance.
