<p>Dear Sergey,</p>
<p><br>
</p>
<p>Try to increase the value of "eps" in PW/src/d_matrix.f90 and then recompile pw.x and hp.x and try again.</p>

<div>Hello,</div>
<div> </div>
<div>I'm computing a U value using HP code for ferromagnetic insulator. After 2 SCF procedures, I'm running HP code, there are 6 q points. When half of the job is done (3 q points), I got this error:</div>
<div>.....</div>
<div>highest occupied, lowest unoccupied level (ev):     8.9241    9.4470</div>
<div> </div>
<div>     Writing all to output data dir ./tmp/HP/PLASTIC.save/</div>
<div>     Done!</div>
<div> </div>
<div> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div>
<div>     Error in routine d_matrix (2):</div>
<div>     D_S (l=3) for this symmetry operation is not orthogonal</div>
<div> %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%</div>
<div> </div>
<div>     stopping ...</div>
<div> </div>
<div>Is it something easy to fix?</div>
<div> </div>
<div>Thank you,</div>
