<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Dear all,<br>
I use Virtual Crystal approximation in WIEN2K09.2. I run "init_lapw" to
set up my case with real atoms, and and change Z in case.struct and
number of electrons in case.in2 after initialisation. The SCF calculations of my case is well
except for some "WARNING"s. The "WARNING" messages are in the case.scf
file:<br>
<br>
:KPT : NUMBER OF K-POINTS: 35<br>
:WARN : WARNING: NE limited by NUME in param.inc<br>
:GMA : POTENTIAL AND CHARGE CUT-OFF 12.00 Ry**.5<br>
......<br>
<br>
:ENE : *WARNING** TOTAL ENERGY IN Ry = -239021.00581451<br>
<br>
<br>
<br>
Such kinds of "WARNING"s are only in three scf-iterations:<br>

<br>
I wonder that is there any trouble in my calculations?<br>
could someone give me any advice?<br>
Thanks in advance.<br>
