3️⃣ Steps to Run Multiple Jobs Sequentially in Abaqus | Abaqus Job Scheduler

Automatic Running of Abaqus multiple Jobs sequentially Banner | Abaqus job scheduler

Are you tired of spending countless hours running multiple Abaqus jobs? In this article, we’ll guide you through automating your Abaqus queue job efficiently. Learn how to generate .inp files, create a customized Abaqus batch file, and utilize the Windows Task Scheduler for an automated Abaqus batch run. Say goodbye to manual job submissions and hello to a streamlined Abaqus job scheduler, Enabling you to Abaqus run multiple jobs sequentially without the hassle. Read on to simplify your job management and save valuable time. You can simulate Abaqus examples, such as writing subroutines or Python scripting, and automate the running of your jobs by joining our ABAQUS course. We take pride in being your CAE Assistant.

Abaqus Job Module: Controlling Your Simulation Run

The Abaqus Job module is the command center for launching and managing your finite element analysis (FEA) simulations. Here, you define the tasks for Abaqus to execute, including:

  • Input file generation: The Job module translates your model definitions (parts, materials, interactions, etc.) from previous Abaqus modules into a text-based input file (.inp) that Abaqus understands.
  • Analysis execution: You initiate the simulation process from here, triggering Abaqus to solve the complex equations governing your model’s behavior.
  • Output control: The Job module allows you to specify the data you want to extract from the analysis, like stress and strain values at specific locations.

1. Introduction to Abaqus Job Scheduler : Generating .inp Files

After changing any parameter of your model, create a job and then in Job Manager window, instead of selecting Submit, just press Write Input:

Writing Abaqus input file | Abaqus job

Repeat that for every job you defined.

Now, you can find as many .inp files in the Working Directory as jobs you defined before, ready for the Abaqus job scheduler and managing Abaqus queue jobs.

Now, It’s time to simplify your workflow and transition to Abaqus run multiple jobs sequentially for increased efficiency.

2. Creating a Customized Batch File | Creating Abaqus Batch Files

Then, we need to create a .txt file (for example, AutoJobRun.txt), enter some commands, and then save the file and change its ending to .bat. First, right click on any empty space and select New > New Text Document:

abaqus batch run | call Abaqus job

Now, Open the created file. You must enter a line like the following for each job:

call Abaqus job=job_name interactive

Where you replace job_name with your selected name for every job:

Call Abaqus job | Abaqus batch file

The phrase interactive is really important to run jobs sequentially and after completing the former job.

Close the file and Save it. Now, we should change its extension to .bat. If you can not see the extension of the files (in Windows 8 and upper), just go to View tab > Options > Change folder and search options. Then, in the opened window, go to the View tab and uncheck the Hide extensions for known file types

Now we have a file named AutoJobRun.bat, which is an Abaqus batch file.

This .bat ending file is called a batch file. A batch file is a script file in Microsoft Windows. It consists of a series of commands to be executed by Windows, stored in a plain text file. Here, you have created an Abaqus batch file scheduling jobs in Abaqus.

3. Automate Running Abaqus Queue Jobs | Abaqus Batch Run

For this purpose, we have to use Windows Task Scheduler. Find the Task Scheduler app in Windows and run it. On the left panel, choose Create Task… Abaqus queue Jobs

Then, in the appeared window, type a name for your task and a description if you wish. Also, select Run whether the user is logged in or not and tick Run with the highest privileges. You should select Windows 10 in Configure for: menu.

Create Task General Tab Setting / Abaqus queue Jobs

Then, switch to the Triggers tab, select New, and choose the desired day and time to Start running jobs automatically:

Create Task Triggers Tab Setting | Abaqus jobs - Abaqus multiple jobs | Abaqus queue Jobs

Switch to the Actions tab, select New, and Browse for Abaqus batch file we created before:

Create Task Actions Tab Setting | Abaqus jobs - Abaqus multiple jobs

And finally, switch to the Conditions tab and tick the Wake the computer to run this task option:

Create Task Condition Tab Setting

With this selection, even if the computer is shut down, it will wake at the selected time. However, I suggest to Hibernate your computer and plugging it in.

Press OK. If the program asks for your account Password, type it.

4. Techniques for Speedy Simulations:

  • Hardware Optimization: Ensure you have sufficient RAM to accommodate your model’s complexity. Utilize multi-core processors by enabling parallel processing in Abaqus. Consider using high-performance computing clusters for exceptionally demanding simulations.
  • Mesh Refinement: A coarse mesh might lead to inaccurate results and longer run times. Conversely, an excessively fine mesh offers diminishing returns and slows down the simulation. Refine the mesh in critical areas where stress concentrations are expected, and employ a coarser mesh in less critical regions.
  • Submodeling: Complex simulations with intricate details can be computationally expensive. Submodeling isolates a specific region of interest with a finer mesh for detailed analysis, while the surrounding area uses a coarser mesh, reducing overall computation time.
  • Simplifications: Evaluate if specific model features are crucial for the analysis. Removing unnecessary details or simplifying complex geometries can streamline the simulation process.

5. Preventing System Hiccups:

  • Close Background Applications: Unnecessary programs running in the background consume system resources like RAM and CPU, potentially slowing down Abaqus. Close any programs you don’t need while running a simulation.
  • Disable Antivirus/Firewall Temporarily: Antivirus software or firewalls might interfere with Abaqus, especially during file I/O operations. Consider temporarily disabling them during the simulation (remember to re-enable them afterward for security).
  • Optimize Virtual Memory: If your physical RAM is insufficient, the operating system utilizes virtual memory on your hard drive. However, hard drive access is much slower than RAM. Ensure you have enough free space on your hard drive for virtual memory to function effectively, but avoid relying solely on it for optimal performance.

By effectively utilizing the Abaqus Job module and implementing these techniques, you can achieve faster simulation run times and minimize system issues during Abaqus analysis.
