A Finite Element Analysis Package for Engineering Application
Our Abaqus license will run out on April 30th, 2024. You will only be able to resume working with Abaqus products if you can bring your own license (see Abaqus - only with own license). Alternatively, you might consider using other Finite Element Analysis (FEA) tools such as Abaqus - only with own license or Abaqus - only with own license from Ansys.

ABAQUS 2019 is the default.
ABAQUS 2018 is the first version with multi-node support.
ABAQUS 2016 is the last version including Abaqus/CFD.

Conditions for Usage and Licensing
You are only able to work with our installed Abaqus products if you can bring your own license (see details below). Alternatively, you might consider using other Finite Element Analysis (FEA) tools such as Mechanical or LS-DYNA from Ansys.
To bring your own license to our systems first follow the steps described in Bring Your Own License(It should be sufficient if our login nodes can access you license server).
Secondly place a file called abaqus_v6.env in your home (~) folder or in your current working directory. Inside that file add the following line:
abaquslm_license_file="port@ip_number_of_your_license_server"
Example Jobscripts
The input file of the test case (Large Displacement Analysis of a linear beam in a plane) is: c2.inp
Distributed Memory Parallel Processing
#!/bin/bash
#SBATCH -t 00:10:00
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=48
#SBATCH -p standard96:test
#SBATCH --mail-type=ALL
#SBATCH --job-name=abaqus.c2
module load abaqus/2020
# host list:
echo "SLURM_NODELIST: $SLURM_NODELIST"
create_abaqus_hostlist_for_slurm
# This command will create the file abaqus_v6.env for you.
# If abaqus_v6.env exists already in the case folder, it will append the line with the hostlist.
### ABAQUS parallel execution
abq2019 analysis job=c2 cpus=${SLURM_NTASKS} standard_parallel=all mp_mode=mpi interactive double
echo '#################### ABAQUS finished ############'
SLURM logs to: slurm-<your job id>.out
The log of the solver is written to: c2.msg
The small number of elements in this example does not allow to use 2x96 cores. Hence, 2x48 are utilized here. But typically, if there is sufficient memory per core, we recommend using all physical cores per node (such as, in the case of standard96: #SBATCH --ntasks-per-node=96). Please refer to Slurm partitions CPU, to see the number of cores on your selected partition and machine (Lise, Emmy).
Single Node Processing
#!/bin/bash
#SBATCH -t 00:10:00
#SBATCH --nodes=1 ## 2016 and 2017 do not run on more than one node
#SBATCH --ntasks-per-node=96
#SBATCH -p standard96:test
#SBATCH --job-name=abaqus.c2
module load abaqus/2016
# host list:
echo "SLURM_NODELIST: $SLURM_NODELIST"
create_abaqus_hostlist_for_slurm
# This command will create the file abaqus_v6.env for you.
# If abaqus_v6.env exists already in the case folder, it will append the line with the hostlist.
### ABAQUS parallel execution
abq2016 analysis job=c2 cpus=${SLURM_NTASKS} standard_parallel=all mp_mode=mpi interactive double
echo '#################### ABAQUS finished ############'
Abaqus CAE GUI - not recommended for supercomputer use!
If you cannot set up your case input files *.inp by other means you may start a CAE GUI as a last resort on our compute nodes.
But be warned: to keep fast/small OS images on the compute node there is a minimal set of graphic drivers/libs only; X-window interactions involve high latency.
If you comply with our license terms (discussed above) you can use one of our four CAE licenses. In this case, please always add
#SBATCH -L cae
to your job script. This ensures that the SLURM scheduler starts your job only if a CAE license is available.
srun -p standard96:test -L cae --x11 --pty bash # wait for node allocation (a single node is the default), then run the following on the compute node module load abaqus/2022 abaqus cae -mesa
