Caspt2 calculation throwing Error in Get_Ln

Hello,

I am currently trying to run a caspt2 calculation on an iron complez with the following input:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 &gateway 
    Coord
    ...
    Basis
    ANO-RCC
    Group
    Nosym 
  &SEWARD 
  &RASSCF
    Spin
      3 
    nactel  
      10  0  0 
    inactive
      94 
    ras2  
      11 
    ciroot  
      1 1
      1
    Outorbitals
    Canonical orbitals
  &CASPT2
    maxiter 
      40 
    multistate
      1  1 
  &RASSI  

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Initially the calculation gave the following error:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  *** Error in MKSRT1 ***
  Insufficient memory
  nBin exceeds limits (nBin>mxBin)

 nBin=                10885
 mxBin=                 2048

 Increase MOLCAS_MEM and try again!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I then increased the memory allocated to the calculation and the program gave me this:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

EOF reached for file=stdin                                                                                                                                                                                                                                                           
#    Error in Get_Ln                                        

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any help would be reatly appreciated!

Thanks,

Ryan

Re: Caspt2 calculation throwing Error in Get_Ln

ANO-RCC is a huge basis set. Are you sure you don't want some reasonable contraction like ANO-RCC-VTZP?

The error looks like something is wrong with the input. Which program is failing, seward, rasscf, caspt2, rassi?

The program is failing in the Gateway section:

Re: Caspt2 calculation throwing Error in Get_Ln

I will try to rerun the calculation with the truncated basis set.
