Abaqus

Abaqus is powerful engineering simulation software and is available for use on the supercomputer.

License

Abaqus is proprietary software and requires a license from Engineering Technical Services (ETS) for use. To request a license, please use this link: Abaqus for Research (ETS).

After a license is obtained, run the following command on the supercomputer to enable it:

echo "academic=RESEARCH" > ~/abaqus_v6.env

Running Abaqus

serial

Abaqus has the capability to run on a single node, utilizing up the maximum amount of cores on the node. Below is an example to include in your SBATCH script for executing Abaqus:

module load abaqus/2023

#Modify below to match your job!
abaqus_opts=(
  job=test_50x50x20_f7
  input=50x50x20_f7.inp
  user=coupled_ue19.f
)
abq2023 "${abaqus_opts[@]}" cpus=$SLURM_CPUS_PER_TASK interactive

parallel

Abaqus has the capability to run across multiple nodes, allowing it to utilize more cores than those available on a single node.

module load abaqus/2023 intel/oneapi
#Modify this to match your job!
abaqus_opts=( 
  job=test_50x50x20_f7 
  input=50x50x20_f7.inp
  user=coupled_uel9.f
  mp_mode=mpi
)
