Description

Abaqus FEA is a software suite for finite element analysis and computer-aided engineering. It contains the products Abaqus/CAE, Abaqus/Standard, Abaqus/Explicit, Abaqus/CFX and Abaqus/Electromagneitc.

Available versions (Euler, old software stack)

Legacy versions Supported versions New versions
6.11 6.13-2, 6.14-1 2016, 2018, 2019

Please note that this page refers to installations from the old software stack. There are two software stacks on Euler. Newer versions of software are found in the new software stack.

Environment modules (Euler, old software stack)

How to submit a job

You can submit an Abaqus job for an input file myjob.inp with the following command.
sbatch [Slurm options] --wrap="abaqus job=myjob [Abaqus options]"

Alternatively, if you have an additional .com file (for instance test.com), which contains Python code, then you would use the job parameter for the .com file and the input parameter for the input file.

sbatch [Slurm options] --wrap="abaqus job=test input=myjob [Abaqus options]"

To submit a parallel calculation you would use the form

sbatch -n 4 [Slurm options] --wrap="abaqus job=myjob cpus=4 [Abaqus options]"

Here you need to replace [Slurm options] with Slurm parameters for the resource requirements of the job. Please find a documentation about the parameters of sbatch on the wiki page about the batch system. You can display all possible command line options for Abaqus, by logging in to the cluster, loading the Abaqus module and running the command

abaqus help
The command line parameters vary for the different Abaqus products.

Example

LSF examples are obsolete. They will soon be replaced with Slurm examples.
As an example for an Abaqus job, we use a mildly nonlinear static analysis that simulates bolting a cylinder head onto an engine block.
[leonhard@euler01 abaqus]$ ls
s4b.inp  test.com
[leonhard@euler01 abaqus]$ module load abaqus/6.14-1
[leonhard@euler01 abaqus]$ bsub -n 4 -W 1:00 -R "rusage[mem=2048,scratch=1500]" "abaqus job=test cpus=4 input=s4b scratch=\$TMPDIR"
Abaqus job.

Please note that you need to request local scratch space from the batch system, when you would like to use the scratch parameter of Abaqus.
