Dear Quantum Espresso users,
I am trying to run the ph.x executable using a simple silicon example which I found online. I first perform the scf calculation and save the results and then use the same outdirectory and prefix when running the ph.x code. However, I keep getting the same error which says: 'Error in routine image_q_irr (1): some images have no rapp' I have attached the ph input file. I would really appreciate it if someone can help explain to me why this is happening. Phonons of Si at Gamma &inputph tr2_ph=1.0d-14, amass(1)=28.0855, prefix='SIPH', outdir='/nfs/11/osu7834/' fildyn='si.dynG', / 0.0 0.0 0.0 Thanks, Adib Samin Adib Samin Postdoc The Department of Aerospace and Mechanical Engineering The Ohio State University -------------- next part -------------- An HTML attachment was scrubbed...
