Application Guide: ABAQUS¶
ABAQUS Licensing¶
ABAQUS is licensed using a combination of Execute Tokens (for compute jobs) and Interactive Seats (for
running an ABAQUS graphical user interface).
Advanced Research Computing fund 175 Execute Tokens and 16 Interactive Seats for general
use on BlueBEAR. Additionally, research groups can purchase their own licences in order to guarantee access to ABAQUS tokens or seats.
The number of Execute Tokens required is dependent on the number of cores being used. This relationship is given as follows:
- \(b\) = base value, i.e. for 1 core (see table below)
- \(N\) = number of cores (equivalent to
--ntasksin Slurm) - \(int\) denotes truncation instead of rounding
An overview of the Execute Tokens required is given in the following table:
| Number of Cores | Standard, Explicit and CFD | Foundation | Aqua and Design |
|---|---|---|---|
| 1 | 5 | 3 | 6 |
| 2 | 6 | 4 | 8 |
| 4 | 8 | 5 | 10 |
| 8 | 12 | 7 | 14 |
| 12 | 14 | 8 | 17 |
| 16 | 16 | 9 | 19 |
| 24 | 19 | 11 | 22 |
| 32 | 21 | 12 | 25 |
| 64 | 28 | 17 | 34 |
| 128 | 38 | 23 | 46 |
Querying ABAQUS Licences¶
Information on the ABAQUS licence features that are available can be found by executing the following command:
Non-BEAR licences
Please be aware that these licence information commands show ABAQUS licence usage across the entire University. Output will therefore include licences owned by specific users or groups, which other users cannot access and which may be allocated to non-BEAR systems.
abaqus licensing r
Information on current licence usage can be found be executing this command:
abaqus licensing ru
(N.B. for both of these commands you will first need to load an ABAQUS module.)
The above command produces a large amount of output. Search for lines such as the following to determine licence availability for the feature that you require:
Users of cae: (Total of 38 licenses issued; Total of 36 licenses in use)
Insufficient Licences¶
Where there are insufficient licences available, a message similar to the following will be displayed in your Slurm output file:
"standard" license request queued for the License Server.
Total time in queue: 600 seconds.
Depending on the potential wait time for an available licence and also your job's walltime, you may wish to consider resubmitting your job at a later time.
