Abaqus

Abaqus is a software suite for finite element analysis and computer-aided engineering.

Abaqus is available as a module on Apocrita.

Usage

Abaqus 2024 is now fully Python 3

Abaqus versions prior to 2024 used a hybrid of Python 3 for the application and Python 2 for the scripting interface. Newer releases from 2024 onwards are fully Python 3 and include a conversion script to convert existing Python 2 scripts (including *.env files) to Python 3 called abqPy2to3. To use it, load the abaqus/2024 module, navigate to the directory containing your scripts and then run:

abaqus python -m abqPy2to3 <script>

To run the default version of Abaqus, simply load the abaqus module:

module load abaqus

For usage documentation, run abaqus -help.

Licensing

QMUL License

QMUL has an Abaqus license for 60 tokens.

Abaqus is licensed for 60 tokens on Apocrita, when running the application you can request tokens via -l abaqus=<number of tokens>.

The following table lists the number of tokens required to run jobs of various core sizes:

Cores Tokens
1 5
2 6
4 8
8 12
16 16
24 19
32 21
48 25

Please be considerate when submitting Abaqus jobs, as these tokens are shared with all users of the cluster. To be efficient with your token requests, we recommend submitting fewer jobs with more cores to not consume all the available tokens.

Example job

Serial job

Here is an example job running on 4 cores and 16G of memory on a single node:

#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe smp 4
#$ -l h_rt=1:0:0
#$ -l h_vmem=4G
#$ -l abaqus=8

module load abaqus
abaqus job=SIM-FILE \
       cpus=${NSLOTS} \
       mp_mode=THREADS \
       scratch=SCRATCH-LOCATION \
       interactive

Replace SIM-FILE with the name of your simulation file and SCRATCH-LOCATION with the temporary directory location. For the fastest performance, we recommend $TMPDIR if there is enough space for your simulation. If not, you may choose /data/scratch/${USER} to use the auto-deleting scratch space.
