Dear All Users,
I was trying to calculate the el-ph coupling.And I followed just as the
example 07 did.
First I run a dense scf calculation and then a scf calculation.
Sencond I run the phonon calculation and it got error message.
I attached the input of mine and the error message below.Although from
the error message I thought there should be DV file written down.Can any one
help me what I was doing wrong.In addition, the error happened just the ph.x
run just started.
Please someone give me some advise about this.
Have a nice day

elph.in
MgB2-elph
&inputph
amass(1)= 24.3,
amass(2)= 10.8,
prefix='MgB2'
tr2_ph=1.0d-14,
alpha_mix(1)=0.5,
iverbosity=1,
fildyn='/MgB2/elph/test/MgB2.dyn',
outdir='/tmp1/',
ldisp=.true,
trans=.true,
elph=.true.
nq1=4,nq2=4,nq3=4,
fildvscf='/MgB2/elph/test/MgB2dv'
/
and the error message
task # 3
from phq_readin : error # 1
El-ph needs a DeltaVscf file
