Altair Hyperworks on Qarnot Cloud

Altair HyperWorks is a comprehensive computer-aided design and engineering (CAE) tool, developed by Altair Engineering. It is used by engineers, designers and analysts in a variety of industries (automotive, aeronautics or even manufacturing) in order to simulate and optimize the performance of products and systems. Altair Hyperworks allows users to simulate multiple physical phenomena, such as structural mechanics, fluid dynamics, and electromagnetism, within a single model.

Qarnot's Altair Hyperworks software contains the following two solvers:

  1. OptiStruct: Solver used in the mechanics of implicit structures (static, vibratory, thermal and optimization). The input file is the .fem template.
  2. RADIOSS: Solver used in the mechanics of explicit structures (shocks, impacts, crashes, large deformations). The input file is the .rad template.

On request, specialized solvers (Altair Manufacturing Solver, HyperLife, HyperLife, HyperXtrude, MotionSolve, Multiscale Designer and SEAM) can be integrated by our teams.

License

To launch an Altair Hyperworks simulation on Qarnot, you need to use your own license. It can be an Altair One license or a license hosted by you.

Altair One: You need to follow this tutorial to retrieve a token with “Anyhost authorization” rights.

Hosted server: Allow Qarnot services to use your licenses. For more details, please contact our team via support-compute@qarnot-computing.com.

From now on, we'll assume that your license setup with us is complete.

Versions

The Altair Hyperworks versions available on Qarnot are available via the catalog.

If you are interested in another version, please email us at support-compute@qarnot-computing.com.

Start a task via the HPC platform

To launch a task by clicking a button from our web interface, you can use this Step-by-Step Tutorial.

If necessary, here is a test case block.fem/. It is a simple topographic optimization simulation on the Optistruct solver. This one comes from Altair One website.

Start a task using the Python SDK

To do this, the prerequisites are:

The following examples will show you in detail how to launch a task using a Python script.

Example: Starting a topographic optimization task with Optistruct

This test case will show you how to launch a topographic optimization simulation on the Optistruct solver, with the test case block.fem This one comes from Altair One website.

Once the file is downloaded, place it in a directory called altair_block_test.

  1. Basic script

Once everything is set up, use the run-altair.py script below to start a minimalistic calculation on Qarnot. If you want to explore more advanced options, the scripts below (“Batch Launch” and “SSH Launch”) may be of more interest to you.

To launch these scripts, simply copy the previous code into a Python script, place it at the same level as the folder Altair_Block_Test then run Python3 run-altair.py & in your terminal. Your file structure should look like this:

├─ altair_block_test/

│  ├─ block.fem

├─ run-altair.py

Make sure you have copied your authentication token into the script (instead of<MY_SECRET_TOKEN>) in order to be able to launch the task on Qarnot. A Pick up herei.

For example, your input data will appear in the web interface such as:

  1. Batch launch script

The script presented below allows you to explore the more advanced features of the platform for a batch launch.

  1. SSH launch script

The script shown below allows you to connect to your container using the SSH protocol.

To launch it, simply copy the previous code into a Python script, place it at the same level as the folder Input and set your SSH key in the settings DOCKER_SSH.

Also, make sure you have copied your authentication token into the script (instead of “MY_SECRET_TOKEN”) in order to be able to launch the task on Qarnot.
Then run the command:
Python3 run-altair-ssh.py & in your terminal.

You should now be able to connect to the host using the information shown in your console. Your test case is available in /share. Go to the directory /share and you can run your test case.

Results

You should now have an altair_block_test-out folder in your working directory on your computer and an altair_block_test-out bucket in Tasq containing all the output files.

You can view directly on tasq some images and log files generated by the simulation that are in your output bucket. Your results will be stored in the altair_block_test-out bucket and can be retrieved in three ways:

For a large quantity of files or more than 5gb For data, it is recommended to use rclone (Linux) or cyberduck (windows). They are two open source S3 bucket management applications.

Additional Information

For more information on Altair solvers, you can consult the community or even the Documentaries section from Altair One. Also, do not hesitate to contact us for an onboarding and a more personalized presentation of our services via: support-compute@qarnot-computing.com.
