Shearing of a lap joint

This Python script and additional files can be used to create models for examples contained in this guide.

This page discusses:

Fetching the Python script

The scripts are included in Abaqus release; you can extract them from the compressed archive files using the abaqus fetch utility.

  • To fetch a script, enter the following command at the operating system prompt: 

    abaqus fetch job=file_name

    where file_name includes the extension .py.

  • To run a script in Abaqus/CAE, do the following:

    1. From the main menu bar, select FileRun Script.

      The Run Script dialog box appears.

    2. Choose the file from the list of available scripts, and click OK.
