Dear all, I'm trying to run matdyn.x for a certain q-grid and, although I get the vectors and frequencies files (which look correctly) I get an error from matdyn.f90 (version 2.1.5) : 'non-analytic term for q=0 missing!". I found that it is related with a logical variable "has_zstar" but I cannot even find its meaning so I don't understand why I'm getting this error. I'll appreciate your comments or help.
Thank you.
