<div dir="ltr"><div><div>Dear Users and Developers <br><br></div>Recently I have
performed a phonon calculation on an ZrV2O7 on 2x2x2 q grid. I used
q2r.x and matdyn.x to calculate the interpolated phonon frequencies at
other q points in Brillouin zone. However I am getting a message while
executing matdyn.x " Max |d(i,j)-d*(j,i)|/D(i.j) " more than 300%
should I continue with this much non-hermitianty in the dynamical
matrix. I googled it but could not et any satisfactory answer. Please
guide me regarding this issue. The interpolated low energy phonon
frequency are how much affect with this. <br>
