Dear Gautam, Try to open the file PW/src/wsweight.f90 and change the value of parameter nx from 2 to 3, or maybe increase eps to 1.d-5 parameter (eps=1.0d-6,nx=2) then recompile pw and ph.
If this does not work, please provide a full input/output and dynamical matrix files so we can have a look. kind regards On 19/11/17 19:45, Gautam Gaddemane wrote: > Hello All, > I am trying to calculate the phonons for monolayer phosphorene and I > used 5*5*1 q points.
