Dear QE developers,<br><br>I found that the vdW-DF2 is defined in funct.f90:<br><br>###############################################<br><pre> else if ('VDW-DF2' .EQ. TRIM(dftout) ) then
! Special case vdW-DF2
call set_dft_value (iexch, 0)
call set_dft_value (icorr, 4)
call set_dft_value (igcx, 13)
call set_dft_value (igcc, 0)
call set_dft_value (inlc, 2)
dft_defined = .true.</pre>
###############################################<br><pre>However, when I performed calculations using vdW-DF2, I noted the the informations of vdW-DF2 in log files (out file) is Exchange-correlation = VDW-DF2 ( 1 413 0 2). <br>
Is the value of iexch in vdW-DF2 redefined? namely iexch=1?<br><br>Regards,<br>WANG<br></pre><br>
