Vibrational frequency analysis stops during construction of vectors

[chandra]

Dear All,

I am calculating the vibrational frequcencies for a molecule (with 40 atoms) using M06-2X functional. But the job stops at following:

--------------------------------------------------------------------
CONSTRUCTING G(a,i)[S(k,l)xi]              -> RHS
              G(i,j)[S(k,l)xi]*S(i,j)chi    -> Hessian

         Maximum core memory set to         1000 MB
         This corresponds to         604 vectors in CAO basis.

Following is my control file and the start-job file.

I have changed the $maxcore value to 1000, 2000 ...5000 but there is no change. Please help me to sort out the issue.

Thank you very much.

Dear All,

With the continuation of the previous message, the vibrational reduced masses is missing in the control file. I am using Tmolex 4.2.1 version to generate the input.  I am not sure why it is not writing into the input file.

Following lines are missing in the control file
$dipgrad    file=dipgrad
$hessian (projected)    file=hessian
$vibrational normal modes    file=vib_normal_modes
$vibrational reduced masses

Is there a way to manually add the vibrational reduced masses into the control file without using Tmolex ?

Regards,
Chandra
