Abaqus

Abaqus can work in both multithreading and multiprocessing (MPI) modes. Below, you can find examples of submission scripts for both modes.

Multiprocessing job (MPI)

1. Load module

module load abaqus

This will enable a bunch of abaqus-related commands:

abq      fe-safe      fe-safe_cl      tosca      tosca_gui
abq2022  fe-safe2022  fe-safe_cl2022  tosca2022  tosca_gui2022

2. Submit abaqus job

If you want to run Abaqus with multiprocessing on a single node, you can submit the following script:

#!/bin/bash
#
#SBATCH --job-name="SC8R_S1_DMB_R"
#SBATCH --time=108:00:00
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=16
#SBATCH --cpus-per-task=1
#SBATCH --partition=compute
#SBATCH --mem-per-cpu=4GB
#SBATCH --account=research-<faculty>-<department>
#
JOBNAME=SC8R_S1_DMB_R1
module load abaqus 
cd $SLURM_SUBMIT_DIR
TMP=$SLURM_SUBMIT_DIR/results_$JOBNAME
mkdir -p $TMP
cp $JOBNAME.inp $JOBNAME.py $SLURM_SUBMIT_DIR/ $TMP
cd $TMP
abq2022 job=$JOBNAME input=$JOBNAME.inp cpus=$SLURM_NPROCS mp_mode=mpi interactive  
abq2022 cae noGUI=$JOBNAME.py

Multithreading job

1. Load module

module load abaqus

This will enable a bunch of abaqus-related commands:

abq      fe-safe      fe-safe_cl      tosca      tosca_gui
abq2022  fe-safe2022  fe-safe_cl2022  tosca2022  tosca_gui2022

2. Submit abaqus job

If you want to run Abaqus with shared memory on a single node, you can submit the following script:

#!/bin/sh
#SBATCH --job-name="abaqus"
#SBATCH --partition=compute
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=1
#SBATCH --cpus-per-task=4
#SBATCH --time=08:00:00
#SBATCH --mem-per-cpu=2G
#SBATCH --account=research-<faculty>-<department>

module load abaqus

abq2022 cpus=$SLURM_NPROCS mp_mode=threads [all your other abaqus parameters here...] 

Running Abaqus interactivly with GUI on a visual node

1. Open remote connection to the visual node

Detailed discussion about visualization nodes can be found here.

a. Connect to DelftBlue and start a "desktop" job:

$ module load 2022r2
$ module load desktop
$ vnc_desktop 2h -- --cpus-per-task=8 --mem=16G --account=research-faculty-department

As a result, you should get a message along these lines:

Reserving a GPU node (partition "visual")

SLURM job ID is 912918
Waiting for job to start running on a node
We got assigned node visual01, waiting for output...
Waiting until VNC server is ready for connection...

VNC server visual01:1 ready for use!

Check which "port number" the system allocated to you, here "visual01:1", i.e. port "1".

b. Open a tunnel to the port above

Open a separate terminal window and open a tunnel to the corresponding port:

ssh -L 5901:visual01:5901 <netid>@login.delftblue.tudelft.nl

c. Connect your VNC client to the local port corresponding to the open tunnel

vncviewer localhost:1

or graphically:

You should be now prompted with your VNC password (not your NetID password!):

Finally, we have our remote desktop up and running:

2. Load necessary modules and run Abaqus GUI

Inside of the remote desktop, open a terminal and type the following:

module load 2022r2
module load visual
module load qt
module load abaqus
module load virtualgl
vglrun abq cae

You should see the following screen:

You are good to go now.
