Sure. Thank you very much Bert. My input file is just the example file provided with NWCHEM 6.0. When I run the calculation, first there is error saying missing nob value. Then I just added the nob=10 in the file. I didn't do any further modifications on the example input file.
The input is in the following


  start
# start or restart directive if a restart run
MEMORY 1000 mb

PERMANENT_DIR /scratch/wenxu/NWCHEM/
# Globally accessible directory which the
# rtdb (*.db) file will/does reside.

Can you post the full input deck so we can test.

Hi Everyone,
    I was trying to run the example file (given in the manual) for Dynamic Nucleation Theory Monte Carlo in NWCHEM6.0. However I got errors constantly. The errors are like following:

everyone should have an open file at this point
********** Setting Up DNTMC Info **********
*******************************************
Made it through the initial config setup
NSPC = 2
NMOLS = 10
TEMP = 243.00 K
MCSTPS= 1.00E+06

Rot Max Disp = 6.00E-02 rad
Restart files written

RMIN = 3.25
RMAX = 12.25

Made it through initialization

 0: ARMCI aborting 0 (0).

I checked the manual everywhere and still can figure out what happened here. Does anyone have some idea about it and help me out. I really appreciate it. Thank you very much.
