<div dir="ltr">Dear users and developers of QE<div><br></div><div>For my work, I need to Fourier interpolate the anharmonic IFCs that I have calculated (using a coarse q-grid) to a denser q-grid.</div><div><br></div><div>In one of the posts about a year back, there was some discussion on Fourier transforming the anharmonic IFCs in G-space to real space, by just adding one more index in the q2r.f90 program.</div>
<div><br></div><div>Extending this thought, I tried using the approach in the matdyn.f90 program to Fourier interpolate and wrote a code for the same. As a check, I used the same q-grid (that I had used earlier to calculate the IFCs using QE) to see if I could get back the IFCs that I had started out with. I was able to obtain only the gamma-point IFCs successfully, whereas for the other points, the values were not matching at all.</div>
<div><br></div><div>I wish to know, if the approach used is correct, or if there is a different approach.</div><div><br></div><div>Any help in this regard, would be appreciated.</div><div><br></div><div style>Thanks in advance!!</div>
