<div dir="ltr"><div><div><div><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></div>Best,<br></div>Sham<br><div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 23, 2017 at 7:34 PM, Evgeniy Gromov <span dir="ltr"><<a href="mailto:evgeniy.gromov@pci.uni-heidelberg.de" target="_blank">evgeniy.gromov@pci.uni-heidelberg.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Dear Developers and Users of Molpro,<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>
