<div>Thank you, Dr. Paulatto. Yes, I paid attention to your note, but the sentence " the second one [of the matrix elements] has the real part in a line and the imaginary in the next" confused me. My observation is like:</div>
<div> </div><div><div>xx_Re, xx_Im, xy_Re</div><div>xy_Im, xz_Re, xz_Im</div><div>yx_Re, yx_Im, yy_Re</div><div>....</div><div>So for a Cartisian pair, say xy, the real and imaginary parts neighbored, and not follow the matrix indices order, but just simply turn to a new row when the column hits 3. I don't know exactly what you wrote the second one of the matrix element refer to. I hope it means the same.</div>
<div> </div><div>And to every experienced d3.x users:</div><div> </div><div>If I want to calculate the phonon lifetime, one X point as in example14 is obviously not enough, I need a q point sampling. In this case, I know ph.x can do the job with the commands, e.g.</div>
<div> </div><div>ldisp= true</div><div>q1=2</div><div>q2=2</div><div>q3=2</div><div> </div><div>But there is no hint about how to implement the same thing with d3.x followed the phonon calculation, I tried to erase the 0 0 1 in the end of d3 script for X point, but the code does not take the mutiple dyn's from phonon outcome and just crashes. </div>
<div> </div><div>I guess d3 still needs some input for q points, but seemingly there is no way to input more than one q point similar to ph.x. It can only accept one q point at the end of the script. I hope I am wrong, otherwise, if I have 100 q points, then I need to repeat for each point 100 times.</div>
