Dear All Users,<br> I was trying to calculate the el-ph coupling.And I followed just as the example 07 did.<br> First I run a dense scf calculation and then a scf calculation.<br> Sencond I run the phonon calculation and it got error message.<br>
I attached the input of mine and the error message below.Although from the error message I thought there should be a phonon calculation before the elph calculation.But it run the elph calculation directely after the scf run have been done in example07 .<br>
I wonder that should I need a phonon calculation before the el-ph calculation after the scf run. And if the answer is yes, why it do not run in example07.<br><br>Have a nice day<br>Deng Pan<br>Nanjing University<br><br>
