Abaqus

This example provides a minimum working example (MWE) for an ABAQUS calculation with a user-defined subroutine.

Distribution

Details on availability, versions and locations of ABAQUS are given on the software.lehigh.edu page. This page also has important notes on allowed uses for the teaching and research license pools; no consulting or other commercial work may be performed using either license pool.

Using ABAQUS

Load Abaqus with Lmod:

module spider abaqus
module load abaqus/2023

Versions

We offer two versions:

• module load abaqus/2019
• module load abaqus/2023

Licensing

ABAQUS Licensing works differently from other licensed software. To run a ABAQUS job, a user needs to checkout tokens from the license server. There are only 85 tokens available for research use. The number of tokens required is based on the number of cpus being used and can be estimated using the formula: M = int(5 x N^0.422).

Please be considerate of other ABAQUS users and do not run multiple single core jobs in parallel. Instead run all your ABAQUS jobs in sequence or serially, each utilizing multiple cores. Research computing does not broker the use of these tokens, and makes no guarantees about availability. They are first-come, first-serve.

Configuration

The ABAQUS configuration is set by a file named abaqus_v6.env. If you need to customize it, you should copy our default file to your home directory:

cp -av /share/Apps/abaqus/2019/DassaultSystemes/SimulationServices/V6R2019x/linux_a64/SMA/site/lnx86_64.env ~/abaqus_v6.env

User-defined routines

The env file is written in Python. It points to Intel Fortran compilers necessary to compile user-defined routines. If you use the stock version, you might see this error:

Abaqus Warning: Keyword (academic) must be set to RESEARCH or TEACHING.
Abaqus Error: The Abaqus teaching license cannot be used to run analyses that
use user subroutines.

If you do, and you are performing research, you should add this line to the abaqus_v6.env file, in your home directory at ~/abaqus_v6.env or in the current working directory (which takes precedence over the copy in your home directory).

academic = RESEARCH

Note that RESEARCH is not a string, hence it does not use quotes.

Warning: The file above comes from version 2019, but this copy of the env file appears to work with Sol Intel compilers in the most recent testing on 2024.10.03. It may be necessary to further customize this file for user-defined routines in order to use the latest Intel compilers, especially after we upgrade the operating system or compilers at some point in the near future.

Example

To test Abaqus, we are using the following procedure:

CEPH=hpctraining_proj
SPOT=$HOME/$CEPH/$USER/tmp-test-abaqus
mkdir -p $SPOT
cd $SPOT
git clone https://github.com/davidmorinNTNU/ABAQUS_subroutines
module load abaqus/2023
cp -av /share/Apps/abaqus/2019/DassaultSystemes/SimulationServices/V6R2019x/linux_a64/SMA/site/lnx86_64.env ~/abaqus_v6.env
echo -e "academic = RESEARCH\n" >> ~/abaqus_v6.env
cd ABAQUS_subroutines/MJC_example/
abaqus double job=example_VUHARD_MJC.inp user=VUHARD_MJC.f verbose=1
