Python scripting in ABAQUS part1 (for beginners)
By watching this Abaqus Python scripting package, you will learn the basics of Abaqus scripting and get a feel for Python. Moreover, the workshops demonstrate how to run optimization and parametric studies, placing your scripts inside loops and varying parameters. You also get an in-depth look into extracting information from output databases and job monitoring. All in all, you will get the knowledge and the confidence to write your own scripts for finite element simulations in Abaqus (FEA python).
Lesson 1- Introduction to Abaqus Python Scripting:
First of all, you will learn why we need to script. Secondly, a full explanation of useful words in Abaqus is prepared for you. Finally, you should know about what role Python plays in Abaqus and why we choose it over other scripting languages.
Lesson 2- Python Language Programming:
This lesson aims to teach everyone the basics of Python language programming, which is a prerequisite for Abaqus scripting. We cover the basics of how one constructs a program from a series of simple instructions in Python. For example, using variables to store, retrieve, and calculate information and core programming tools such as functions and loops, etc.
Lesson 3- Starting of Scripting:
This lesson will teach you how to run a script, both from within Abaqus/CAE and from the command line. You will receive a detailed explanation of Abaqus PDE. We’ll introduce you to different types of files applied in Abaqus Python scripting, including replay files and macros. You will be able to refer to the Abaqus documentation for using the built-in scripting method for your own simulation.
Workshop 1- simulation of a cantilever beam (Abaqus Python):
In this chapter, we go through a simple example of a cantilever beam to start scripting. You will work through all the steps in creating and setting up a finite element simulation in Abaqus using a Python script. You’ll discover how to use Notepad++ in addition.
Workshop 2- Running a number of jobs sequentially.
In this tutorial, we show you how to run a number of jobs continuously. You’ll be able to keep track of input files in subfolders of your directory and store simulation files in their own directory.
Workshop 3- scripting a 3D Truss of frame of I beam:
We analyze a 3D truss made up I-beam in this workshop. The example covers topics such as parameterization, creating datum planes and datum lines using a script. You will also learn to create a line load by using the Region() method a little differently to return a set-based region as opposed to a surface-based one. In addition, you will learn how to design complex and repetitive structures in Abaqus using Abaqus Python scripting.
Workshop 4- scripting of Bending a Planar shell:
In the last workshop, we will get familiar with another advantage of Abaqus scripting which is optimization by placing the bulk of your script inside of a loop and iterating through it. Additionally, you will use the created report files to execute some of the most common file handling (input/output) operations. During the process, you will be exposed to try-catch blocks, which are used to catch exceptions. You will also learn how to change the color of interesting parts in the viewport using a script, expanding your expertise in post-processing.
It would be useful to see Abaqus Documentation to understand how it would be hard to start an Abaqus simulation without any Abaqus tutorial. It should be mentioned it is the first part of the Abaqus Python training package; if you want to get more advanced information about Abaqus Python scripting (FEA Python), you can click Python scripting in ABAQUS Part 2.
Python is a popular computer programming language used to develop software and websites, automate processes, and analyze data. Since Python is a general-purpose language, it may be used to develop a wide range of programs and isn’t tailored for any particular issues.
Python is a dynamic, bytecode-compiled, and interpreted language. Variable, parameter, function, and method types are not declared in the source code. You lose the source code’s compile-time type checking but gain short, flexible code as a result.
What are the basics of Python?
- Properties. Python is implicitly and dynamically typed, so you do not have to declare variables. …
- Data types. Let’s move ahead to data types. …
- Strings. Let’s move on to strings. …
- Flow control statements. …
- Functions. …
- Classes. …
- Exceptions. …
- File I/O.
The following are some of the advantages of Python:
- Easy to Code. Python is a very high-level programming language, yet it is effortless to learn. …
- Easy to Read. …
- Free and Open-Source. …
- Robust Standard Library. …
- Interpreted. …
- Portable. …
- Object-Oriented and Procedure-Oriented. …
In order to interface with and automate pre- and post-processing tasks, activities, processes, or more generally, 3rd party Python functionality, Abaqus is provided with a Python AP.
An application programming interface (API) to the models and data utilized by Abaqus is the Abaqus Scripting Interface. The Python object-oriented programming language is extended by the Abaqus Scripting Interface, and Abaqus Scripting Interface scripts are Python scripts.
A script is a piece of code created in a high-level programming language that executes pre-existing operations automatically. It is a potent tool that enables you to combine Python’s strength with the capability of Abaqus’ Graphical User Interface (GUI).
Main tasks can be done using python in Abaqus
- Exactly repeat what is done before
- Modifying a parameter
- Looping over a parameter
- Modifying a location
- Changing the (imported) geometry
- Making a script generally applicable
If you want to learn finite element analysis using Python ( FEA Python ), getting more information about the Abaqus software and its abilities is better. Usually, Python is not directly used for finite element analysis, and Abaqus is more often applied for FEA (finite element analysis) instead of Python.
