ABAQUS is installed on IIT Delhi HPC cluster. You need to create a PBS script file and place it in a folder with ABAQUS environment file and ABAQUS input file.

Sample PBS script file is given here

It looks like this underwritten code.

#!/bin/sh 

#PBS -N pranjalm

#PBS -m bea

#PBS -M yourentrynumber@iitd.ac.in

#PBS -l select=1:ncpus=4:mpiprocs=4

#PBS -l walltime=01:00:00

#PBS -q low  # replace "low" with "standard" or "high" based on your project budget

#PBS -P civil #"(replace "civil" with your department/project code)"

#PBS -l software=abaqus2017

# load/unload the appropriate modules

module unload OpenMPI                # Abaqus uses it's own MPI libraries

module load apps/abaqus2017			 # Abaqus 2017 as well as Abaqus 6.14 is available in IIT Delhi

module load suite/intel/parallelStudio/2019 # parallel studio for running and subroutines

 
# Change to the working directory

cd ${PBS_O_WORKDIR}



# Run abaqus

time abaqus cae noGUI=data_ext.py  # Abaqus python script running code; #comment out the lines which you don't want to run.

time abaqus job="inp_file.inp" user="subroutine.for" analysis cpus=4 interactive # Abaqus input file with a subroutine (place the subroutine in the same folder)

time abaqus job="inp_file.inp" analysis cpus=4 interactive # Plain Abaqus input file only

wait

Sample ABAQUS environment file is given here

This file will go as it is in your directory.

                         'ABA_ADM_MINIMUMDECREASE')

This will allow you to perform parallel programing operations on ABAQUS.

Above procedure works both on Windows and Linux systems.
