<p>OK so you have transition metal elements surrounded by ligands
(S, Se) ...</p>
<p>For copper, it depends if its oxidation state is +2 or +1,
leading to 10 and 9 electrons in the Cu-3d states, respectively. <br>
</p>
<p>For Manganese you have to use DFT+U or DFT+onsite hybrid
functional or full hybrid if not metallic. <br>
</p>
<p>For zirconium, you should have no difficulties. <br>
</p>
<p>I cannot say more without the chemical composition ... <br>

I guess you do all wrong. A wrong command (even one

spoil the calculations.<br clear="none">
<br clear="none">
a) If your compound is metallic, it is very doubtful that
a hybrid <br clear="none">
calculation is good. Hybrid-DFT is not good for metals.<br
clear="none">
<br clear="none">
b) runsp_lapw -hf -ec -f 1 0.0001 -cc 0.001 -NI<br

<br clear="none">
This command has several errors. What should that be:<br
clear="none">
-ec -f 1 0.0001 ????<br clear="none">
And I doubt that a non-parallel (without -p) calculation
runs <br clear="none">
meaningfully for 200 cycles with -hf. This would run VERY
long, unless <br clear="none">
your k-mesh is very small.<br clear="none">
<br clear="none">
c) You said you did geometry optimization "successfully" !
?<br clear="none">
<br clear="none">
did you use runsp -min -fc 1 ... for this purpose
???<br clear="none">

Did you check that the forces were small at the end in
