[Pw_forum] Is the results of structural relaxiation by pwscf accurate?

[李晓川]

dear all
       According to my trying with different software,i found that there is a 
large difference between relaxiation with pwscf and other software(e.g.vasp and 
castep),So i want to know wh ether the relaxiation of pwscf is reliable? And 
can  you provide some suggestions?
