In any case, do:<br>

top does it show a running lapw1 ? Is it using (near 100%) cpu time. ?<br>
Is there enough memory on this computer ?<br>

and check case.output1(up ?)<br>
<br>
It lists every k-point (matrix size and cpu-time. So even from a partial output1 file you<br>
should see how long one k-point takes and can estimate how long all should last.<div><div class="h5"><br>

Dear Professor Blaha and wien2k community,<br>
<br>
I am working on a structure composed of Fe, Se, O, H and Li atoms, the initialization steps for the SCF calculations proceeded without any problem, though after almost<br>
a week of running the calculations nonstop, the first iteration of the SCF cycle has not yet been completed, it is still at the lapw1 stage.<br>
I have worked on other compounds of rather higher complexity and never have faced this type of problem, I would truly appreciate your assistance in resolving this issue.<br>
<br>
I have attached my case.struct file below and in the initialization procedure I have used a separation energy of -6 Ry, 1000 k- points and an rkmax of 3 because of the<br>
existence of hydrogen (I have also tried rkmax 5).<br>
<br>
with regards,<br>
<br>
