[Pw_forum] vc-relax

[mohaddeseh abbasnejad]

Dear all,

I was trying to do "vc-relax" for an orthorhombic unit cell consisting of 24
ions.
I also put "nosym=.true.".
At the end, I received this error:

" End of self-consistent calculation
 convergence NOT achieved after 100 iterations: stopping "

Would you please help me?

Yours,
Mohaddeseh
