Warnung

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. Based on ABAQUS naming conventions and input style formats open-source projects like www.calculix.de might be an option, too (OpenMP parallel, MPI is experimental https://www.feacluster.com/calculix.php).

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 your 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="

...

Info
To use Abaqus you need to mail support[at]hlrn.de and ask to become a member of the UNIX group abaqus.

You can check your group membership by calling groups.

Usually, there are always sufficient licenses for Abaqus/Standard and Abaqus/Explicit command-line based jobs. In contrast, we only offer 4 licenses of the interactive Abaqus/CAE (GUI). If you add the flag "#SBATCH -L cae" to your job script, the scheduler starts your job only, if CAE licenses are available. You can check the available CAE licenses yourself with: scontrol show lic

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
