Abaqus FEA is a software suite for finite element analysis and computer-aided engineering.

Using your own license[edit]

Abaqus is available on Compute Canada clusters, but you must provide your own license. In your account, create a file named $HOME/.licenses/abaqus.lic containing this single line:


File : abaqus.lic

prepend_path("LM_LICENSE_FILE","port@server")


...replacing port@server with the port number and name of your Abaqus license server.

Your license server must be reachable by our compute nodes, so your firewall will need to be configured appropriately. This usually requires our technical team to get in touch with the technical people managing your license software. Please contact our technical support and we will provide a list of IP addresses used by our clusters and obtain the information we need on the port and IP address of your server.

Cluster Batch Job Submission[edit]

Below is an example submission script for a small Abaqus Explicit job running on four cores:


File : file.txt

#!/bin/bash
#SBATCH --account=def-account  # specify some account
#SBATCH --time=00-06:00        # days-hours:minutes
#SBATCH --mem=2500M            # total memory on node
#SBATCH --cpus-per-task=4      # match to cpus below
 
module load abaqus/6.14.1
unset SLURM_GTIDS
export MPI_IC_ORDER='tcp'

abaqus job=Job-SBS-ALU-EXPLICIT input=SBS-ALUMINUM-EXPLICIT.inp memory="2 gb" scratch=$SCRATCH cpus=4 interactive


To get a list of available Abaqus' command line options, load the abaqus module and run command: abaqus -help | less.

Site Specific Usage[edit]

Sharcnet License[edit]

Sharcnet provides a small but free license consisting of 2cae and 21 execute tokens with usage imposed limits 10 tokens/user and 15 tokens/group. It is available on a first come first serve basis and mainly intended for testing and light usage before deciding to purchase dedicated tokens. The license can be used by any Compute Canada member but only on SHARCNET hardware. Such hardware includes gra-vdi for running abaqus in full graphical mode and graham cluster for submitting compute batch jobs to the queue. Before you can use the license you must submit a ticket requesting access. To do this open a ticket at <support@computecanada.ca> and requst access, include a copy/paste of the following License Agreement statement specifying your full name and username in the designated locations. Every user must do this, it cannot be done by a PI for a group (including PIs who have purchased their own dedicated tokens).

License Agreement[edit]

----------------------------------------------------------------------------------
Subject: Abaqus Sharcnet Academic License User Agreement

This email is to confirm that i "_____________" with username "___________" will
only use “SIMULIA Academic Software” with tokens from the SHARCNET license server
for the following purposes:

1) on SHARCNET hardware where the software is already installed
2) in affiliation with a canadian degree-granting academic institution
3) for education, institutional or instruction purposes and not for any commercial
   or contract related purposes where results are not publishable
4) for experimental, theoretical and/or digital research work, undertaken primarily
   to acquire new knowledge of the underlying foundations of phenomena and observable
   facts, up to the point of proof-of-concept in a laboratory    
-----------------------------------------------------------------------------------

License Server File[edit]

[gra-login1:~] cat ~/.licenses/abaqus.lic
prepend_path("LM_LICENSE_FILE","27050@license3.sharcnet.ca")

Check License Server[edit]

While the below steps are shown in the context of checking the sharcnet license server, in principle they can be used to check any server specified in your abaqus.lic file:

ssh graham.computecanada.ca
module load abaqus

1) Now you can check the complete status of the sharcnet abaqus license server by running:

abaqus licensing lmstat -c $LM_LICENSE_FILE -a

2) If your research group purchased tokens, their corresponding reservations can be shown by doing:

abaqus licensing lmstat -c $LM_LICENSE_FILE -a | grep groupname | grep RESERVATION | head -n2

3) To report your current token usage and compare with the total in use by all other users, including reservations:

abaqus licensing lmstat -c 27050@license3.sharcnet.ca -a | grep  "Users of\|$USER"

Core to Token Mapping[edit]

CORES  1   2  3  4   6   8  12  16  24  32  48  64  96 128
TOKENS 5   6  7  8  10  12  14  16  19  21  25  28  34  38

where TOKENS = floor[5 X CORES^0.422]

Remote Visualization[edit]

First install the TigerVNC client on your desktop as described in VNC. Once logged in start abaqus as follows:

  1. Connect to gra-vdi.computecanada.ca with TigerVNC
  2. module load SnEnv
  3. module load abaqus
  4. abaqus cae

Western License[edit]

The Western site license may only be used by Western researchers with hardware located on Western's campus such as the Dusky legacy cluster. Graham and gra-vdi are excluded since they are located at Waterloo (use the Sharcnet License for these systems as described above). Contact the Western abaqus license server administrator (located in Robarts) to make arrangements before attempting to use the Western abaqus license. Submit a ticket to Compute Canada support to request the admins contact information if necessary. You will need to provide your Compute Canada username and likely make arrangements to purchase tokens. If you are granted access request the port and server values and enter them into your abaqus.lic file as shown in 1) near the top of this wiki which will in turn be used by the Compute Canada module on dusky when it loads.
