ABAQUS – A suite of powerful engineering simulation programs, developed on the finite element method, which solves problems ranging from relatively simple linear analyses like beam analysis to the most challenging nonlinear simulations like crashworthiness of a car.
Why use Scripting?
The main and fundamental purpose of scripting is to access the functionality of ABAQUS/CAE. It is an Application Programming Interface (API) to the models and data used by ABAQUS. This is basically the extension of Python Object-Oriented Programming and hence the scripts are called Python Scripts.
Using this API, user can do the following:
Advantages of using Scripting over GUI
The best instance for this is material modelling. The user can create a material model script ready and utilize it multiple times in creating the materials inside the GUI. Instead of creating the material with all its properties every time, the user can just run the script and import the material at one go.
The user can create a script that modifies the geometry and analyzes the same every time incrementally. Along with this, the same script can be used to read and display the output for every change in the geometry.
In general, ABAQUS provides the user with good quality and quantity of output data. If needed, the user can modify and/or create a new output parameter through the scripts and visualize the results.

As we can observe from the above images, instead of defining the material with individual data in each window and repeat the process, the user can import one script file and create the same material at a single instance.
Along with this, the user can also import multiple materials at a time into the ABAQUS environment using scripting. The example is as follows.
