[Pw_forum] Question on the calculation of MgB2 with distorted lattice.

[张 洪彬]

Dear all:
  I am now trying to estimate the e-p coupling by the deformation 
potentials, especially the E2g mode. However, I artificially add a change 
to both the B atoms coordinates following the moving behaviour of the E2g 
mode, and did a scf calculation with no problem, but when I want to get the 
band structure by a nscf calculation, there was an error like this:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

from Efermi: error #1
unexpected error
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Besides, using ABINIT I can get almost the same band structure with those 
reported. Please tell me why?
Thank you in advance.
