Dear QE experts,

   Is there any module in Quantum Espresso which will optimize geometry 
with pressure?

   Suppose I want to modify an ambient pressure structure to 10 GPa 
pressure structure, is it possible in Quantum Espresso.

   Please note, "press" flag in "vc-relax" calculation not worked for me. 
Relaxed and unrelaxed structure gave same band structure. Hence there is 
no effect of pressure.

with best regards
