Dear Heiko Dumlich: Thank you for your suggestions. I have checked the input file, it seems ok, no spelling mistake and wrong structure. So what I should do is add *"%block GeometryConstraints position from 1 to 6 (This is the gold number )

Dear Fen Hong, you should freeze the gold atoms axis perpendicular to the plane. The problem is that you just put one layer of gold atoms. This means there are no more layers to counteract the force of the adsorbed molecule. If there were more layers in your simulation then you would see a dif

In fact,I did not freeze it. You mean it is necessary to freeze it when do the calculation? But finally we should unfreeze it,right? On Thu, Jan 14, 2010 at 12:25 PM, Christopher Rowan wrote: > Maybe you want to freeze the gold surface atoms? > > Chris Rowan > > 2010/1/13 Min Gao > > Dear all,

Dear Marcos: I have confirmed with the developer of that part (Daniel Sanchez) and his answer is: Yes, the same Ueff will give the same final results. The current implementation follows the work of Dudarev et. al. The plan is to change it for a more rigorous implementation in a future, though.

Akram, In principle all you have to give siesta is the atomic coordinates and the basis set. The kind of hybridization will come from self-consistency and atomic relaxation. Pseudos should not depend on the kind of system you want to calculate - in principle, it's a "one size fits all" element in

Dear all, I need help eagerly! I am working on polyacetylene and I want to know how should somebody consider sp, sp^2 or sp^3 hybridization in calculation ( in generating the pseudopotentials, in PAO basis or ). I would be sincerely grateful if you could guide me. regards; Akram Keyhannezhad
