[Pw_forum] vc-relax for a Magnetic atom

[Huiqun Zhou]

I just can't understand why you need to do vc-relax to an single atom system.
Usually, you need to put the atom in a big enough supercell, do you think
there are any geometric parameters need to be optimized in such a case? 

What you need to do is to determine how big the supercell should be.

  Dear All
   
  I want to calculate the vc-relax for a magnetic atom, like the manganese Mn.
   
  I try to do it, but always , i obtain errors and the calculation is not good at all.
   
  So what should i add in my input to obtain a better calculation for Mn.
   
  Can anybody send for me to ali.allam2 at hotmail.com an example for the vc-relax for a magnetic atom.
   
  Thanks 
   
  Ali
