<div dir="ltr"><div><div>Dear Users of Molpro,<br><br>I am a novice user of Molpro and I can not deal with some things:<br><br>1. I intend to perform nevPT2 calculations. <br>The manual says: "NEVPT2 has been implemented in two variants both of which are present in MOLPRO, these are the strongly contracted (SC) and the partially contracted (PC) variants. (...)"<br>
<br><b>How in the input file I can indicate what variant of nevPT2 method I want to use (SC or PC)? </b>I cannot find in manual any informations about it.<br><br>2. Properly choice of MEMORY value in case of both - nevPT2 and CASPT2 calculations is huge problem for me. For example when I declare the value 450 M in CASPT2 calculations are terminated with an error:<br>
<br><i> Number of contracted N-1 electron functions: 29478<br> insufficient memory available - require 830945115 have 217463053<br> the request was for real words<br><br> GLOBAL ERROR fehler on processor 0</i><br>
<br>After increasing this value to 1580 M, in the same moment calculations are terminated with an error:<br><br> <i>Number of contracted N-1 electron functions: 29478<br> insufficient memory available - require 2447745300 have 1092332185<br>
the request was for real words<br><br> GLOBAL ERROR fehler on processor 0</i><br> <br>I don't understand that. Moreover - in nevPT2 calculations information often is:<br>insufficient memory available - require ***********<br>
