Dear Espresso users I have performed a phonon calculation of an oxides on 4*4*2 q grid. I am using pw.x , ph.x; q2r.x, matdyn.x and lambda.x to calculate the phonon-electron coupling i obtained the positive frequencies, but i get the following message during the lambda.x commnde forrtl: No such file or directory forrtl : severe (29): file not found, unit 4, file/home/halima/MgB2/.../fort.4 lambda.x 00000000000000049 Unknown
libc.so.6 unknown any suggestions to solve this problem cordially i can't explain why i get negatives frequencies Kindly suggest me the possible ways where I can solve this. cordially -- H.ZAARI PhD Student in laboratory of magnetism and physics of high energy Faculty of Sciences in Rabat - Morocco Email: * halimazaari at gmail.com <boujnah.mourad at gmail.com>* -------------- next part -------------- An HTML attachment was scrubbed...
