Dear Sham,<br>
<br>
Thanks very much for your reply. Yes, I meant the previously
existing limit for the number<br>
of closed shell inactive but correlated orbitals in MRCI. This is
supposed to have been removed in molpro2012.<br>
However, I still get this message "TOO MANY ACTIVE ORBITALS: ...",
when running a mrci calculation<br>
with molpro2012.1.<br>
<br>
My input for mrci is:<br>
<br>
{ci;wf,86,1,0;save,3010.1;state,6;noexc}<br>
{ci;wf,86,1,2;save,3020.1;state,6;noexc}<br>
!<br>
lsint<br>
!<br>
{ci;hlsmat,ls,3010.1,3020.1}<br>
<br>
I tried to replace "ci" with "mrcic" as you suggested but the job
crashed with an error,<br>
which indicated that it doesn't "know" the keyword "mrcic". Also in
the manual<br>
I didn't find such a keyword, though it is mentioned that there is
"a new internally<br>
contracted MRCI code: MRCIC ...". Do you have any example of input
with "mrcic"<br>
keyword?<br>
<br>
Best regards,<br>
Evgeniy<br>

<div>Dear Evgeniy,<br>
<br>
</div>
There is no compiler option for this. The limit of 32
correlated internal orbitals (closed + active) exist for
methods RS2 and MRCI in molpro. Two new related methods,
RS2C and MRCIC, have been also available in molpro. For
these programs, the limit is now 32 active orbitals and
there is no limit on number of closed orbitals. The new
MRCIC program works only for one state (typically ground
state with multi-reference character).<br>
</div>
<br>
</div>
<div>You can use them with {rs2c;...} or {mrcic;...} just like
old programs.<br>
<br>

<br>
If I am not mistaken, the limit of 32 active orbitals is
supposed to have been (quasi) removed in molpro 2012.1.<br>
I vaguely remember that some trick is however needed before
or during the compilation to actually get rid<br>
of that limit. I will very much appreciate a hint for that
trick.<br>
Many thanks!<br>
