The Abaqus FEA is a software suite for finite element analysis and computer-aided engineering, originally released in 1978.
IMPORTANT: Do not run Abaqus from sbatch jobs. Use an abq* command instead. Unlike other modules, Abaqus FEA has been directly integrated with SLURM
Loading Modules
To use Abaqus/2024 on the cluster, you will need to first load the abaqus/2024 module using this command:
module avail abaqus
module load abaqus/2024
Running Abaqus
Abaqus jobs are managed by SLURM. To submit a job to Abaqus, transfer your model input file to the cluster and run the following command:
abq2024 job=FILE que=general:fslocal
where
abq2024
Is the command (case sensitive) to invoke Abaqus 2023.
The name of your input (.inp) file without the file extension.
Runs the Abaqus simulation on a local file system using the general partition (you can use any of the partitions from sinfo -o %P)
The simulation will run on another compute node and copy the result files upon completion.When que=general:fslocal is specified, any node from any hardware architecture can be assigned. If certain abaqus code needs specific libraries or hardware, the que declaration will not work and the bash submission script route would need to be performed. Please see the Bash Script section further down in this knowledge base article.
Adding a user subroutine
If a user subroutine is adopted in the Abaqus model, run the command with "user" option.
where
Is the file name of the user subroutine written in FORTRAN.
CPU parallel analysis
If parallel computing is needed, run the command with "cpus" option.
where
Will request five CPUs to run the job. More CPUs will require more Abaqus license tokens to run.
Unexpected end of file error
When submitting an abaqus job, you will see:
These sh warnings are harmless, and you can ignore them.
Checking job status
Run this command:
where
Is the name of the status file.
If you are running your job in a local file system, then you have to change the directory the specific folder and specific node to check the status of your job.
Normally when the simulation is finished, the HPC will send you an email showing the simulation is completed successfully or exited with error.
Terminating an Abaqus Analysis
If an analysis job needs to be terminated before completion, find the Job ID with this command.
which will list all the jobs that are running. Then run this command to kill a specific job.
where
Is the SLURM ID number of the job you want to kill
Bash Scripts
The following is an example batch submission script, my_job.sh.
To run the executable abaqus with input file use the job=inputfilename.inp syntax.
The script requests 126 cores
#!/bin/bash
#SBATCH --job-name=abaqus_test
#SBATCH --nodes=1
#SBATCH --ntasks=126
#SBATCH --partition=general
#SBATCH --constraint='epyc128'
#SBATCH --mail-type=END
#SBATCH --mail-user=first.lastname@uconn.edu
module load intel/oneapi/2022.3 abaqus/2024
abq2024 job=inputfileName.inp user=subroutinehere cpus=$SLURM_NTASKS interactiveAbaqus CAE/Viewer
To be able to launch the CAE or Viewer for Abaqus 2024, a X session would need to be set up when logging into the cluster. Once a terminal session has been loaded with X enabled (either through MobaXterm or ssh -X), a srun or fisbatch job would need to be submitted to the cluster.
Example srun command to submit to the general partition:
Example fisbatch command to submit to the general partition:
Once the job has been submitted and a node has been allocated, the abaqus/2024 module would need to be loaded.
After the abaqus/2024 module has been loaded in the fisbatch session, the GUI can be launched by using either any of the following commands:
To enable the Abaqus/CAE GUI with mesa drivers:
