3 methods to use python in Abaqus for absolute beginners

Description

Before explaining how to use python in Abauas, it is necessary to know what Abaqus is.

Abaqus:

Abaqus is an FEA software used to analyze models with high complexity. The provided options by this software create a great environment to study various models. Not only solid mechanics but also thermal and fluid mechanic models can be simulated in this software. It is worth to mention the fluid mechanic model was separated after Abaqus 6.16 and since version 2017 the company began developing an independent solver for it. In order to increase the complexity of models, engineers can use FORTRAN to develop subroutine code and Python to create a model by scripting.

Scripting Python in Abaqus:

Imagine you want to create a part with holes randomly distributed inside it. You need to bring a calculator and a piece of paper to find some random number as the center and radius of those holes. Another option is to use Matlab code or any other coding language to find those random values. However, after finding those values you still need to create those holes inside your model. You need to modify your part at least once per each hole. Fortunately, Abauqs provided Python scripting to avoid it. You can easily create your code there and use the provided function to create and modify those holes inside your part. Consequently, you don’t need to do it by clicking and modifying your part. You can develop a code in Python to do the job for you.

More examples of Python in Abaqus:

1- For the shot peening process you need to shoot more than 100 balls to a designed surface in a short amount of time. You need to place the ball randomly and even with random speed. Thus, you need to use Python coding to place and define an initial speed for each ball.

2- You want to do a parametric study to find a critical load for a designed part. You need to change the value and the trend of the applied load and run your model.

3- You want to add material for an AM process. You need to use the element birth technic for each step. The whole model requires more than 30 steps and interactions. Thus, you need to use Python to define them.
