Dear Iurii,
<div class=""><br class="">
</div>
<div class="">I rerun the hp.x using q-e-qe-7.0. I could avoid the same crash if I use a dist_thr=7.0 in the hp.in which seems to me quite large. Also some of the U parameters come out negative and some are "**********” which I guess they are too large for
the format.</div>
<div class=""><br class="">
</div>
<div class="">I will keep digging into the code to see if I can find the source of this crash.</div>
<div class=""><br class="">
</div>
<div class="">Cheers,</div>

Dear Iurii,
<div class=""><br class="">
</div>
<div class="">Thank you for taking the time to look at my files. Yes, I did recompile hp.x first and then pw.x for QE-6.5. I did not realize that the dist_thr existed. The documentation online for QE is version 7.0 for QE and 6.6 for hp.x.</div>
<div class=""><br class="">
</div>
<div class="">I will try the latest version of the code with dist_thr and that will hopefully resolve the issue.</div>

<div class="">I very much appreciate your suggestion.</div>

</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">You are using QE6.5. This is quite old. I recommend to use the latest version QE7.0 because it has different bug fixes.</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">I am surprised that increasing eps_dist does not solve the problem. Are you sure you do it properly? Did you recompile pw.x and hp.x after making this change? Note that in QE7.0 you do not need to do
that because there is a new input parameter for hp.x which<span class="Apple-converted-space"> </span> is called dist_thr which replaces eps_dist. So in QE7.0 there is no need to recompile the pw.x and hp.x codes, instead just set dist_thr in the hp.x input
and change its values from the default 6.d-4 (Bohr) to some larger value.</div>

<div class="PlainText">Dear QE Community,<br class="">
<br class="">
I am running Hubbard U on a relaxed slab of 96 atoms with a 25Angstrom vacuum. I generated all the response function matrices (using sum_pertq) but when using compute_hp to collect all the chi0 and chi matrices, I get the following error:<br class="">
<br class="">
Many lines similar to the ones below<br class="">
<br class="">
Missing chi element for: na= 288 nb= 89 dist= 21.669460<br class="">
<br class="">

<br class="">
Possible solutions:<br class="">
1. Relax better the structure (in order to have more accurate inter-atomic distances)<br class="">
2. Increase the value of the parameter eps_dist in PW/src/ldaU.f90,<br class="">
then recompile the pw.x and hp.x codes, and re-run the HP postprocessing step<br class="">
by setting compute_hp=.true. in the HP input.<br class="">
<br class="">
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br class="">
Error in routine reconstruct_full_chi (1):<br class="">
Reconstruction problem: some chi were not found<br class="">
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br class="">
<br class="">
The structure is relaxed and the forces are quite small with zero stress on the cell.<br class="">
<br class="">
I increased eps_dist to 0.1 and still get the above error.<span class="Apple-converted-space"> </span><br class="">
<br class="">
Any suggestion as to how to avoid this error is deeply appreciated.<br class="">
