Hello People,

I want to relax CoPt bulk material. It has face-centered tetragonal (tP4) 
structural type. The relaxation is always finisihing after 1 scf cycle and 0 
bfgs step. The forces are always zero. I mean the system is not relaxing. I 
googled the problem and I tried something in input, nevertheless I failed for 
every try. What am I doing something wrong? Do you have any suggestion or 
comment or web page??
I am using svn version with latest updates.
Here is my input file:?
