Description
Linking ABAQUS and MATLAB
In the “Linking ABAQUS and MATLAB” package, firstly, we get you some explanation about optimization. We encounter various optimization(Find more information about optimization from this link) problems in engineering that their represented models are constructed through FEA employing commercial software such as ABAQUS, Ansys, Comsol, etc. However, to perform the optimization process, the optimization algorithm (e.g. genetic algorithm, particle swarm optimization, ant colony, etc.) is usually coded in other environments like MATLAB. Nowadays, MATLAB is a widely accepted and easy-to-use software among engineers to code their optimization algorithms.
Therefore, it seems that the missing part is the link between MATLAB and the commercial FEA software (like ABAQUS) to close the optimization loop.
In this package, one way to link between the two software is described by conducting a 2D topology optimization case study. BESO is a heuristic topology optimization technique that we will go briefly through it in the package. By following this package, you will learn tricky points to create a link between ABAQUS & MATLAB, and then after you can customize this method to apply it to your very specific problem.
It should be mentioned, optimization also could be done with Scripting in python. You can find the helpful package about scripting here.
Users ask these questions
In social media, users asked questions regarding linking Abaqus & MATLAB, which we answered a few of them; you can see them below.
I. Abaqus and MATLAB
Q: I’m using Abaqus to simulate a pillar with brittle material subjected to nanoindentation, with the goal of determining the stress required for an unstable crack. I’m creating the model with a Matlab file and running the simulations with a job.inp file. I can choose the mesh and radius of the pillar in Matlab, but I’m stumped as to why, with the same job parameters and mesh, I get different load trends for different pillar’s radius.
Thank you for any suggestions.
A: Hello,
I think you get a different trend for the load because your model is nonlinear, so you shouldn’t necessarily obtain the trend you expect, and it could be different. Moreover, why did you use Matlab for meshing anyway? With the ABAQUS itself, you could more easily mesh the model and optimize it, refer to this link: https://caeassistant.com/product/python-scripting-in-abaqus-part1/
If you really need to use Matlab, I think this link might help you as well: https://caeassistant.com/product/linking-abaqus-matlab-for-beso-topology-optimization/
II. Importing data from MATLAB to ABAQUS
Q: Hello, I have a dataset with x,y,z point coordinates from a CMM surface measurement. How can I process the surface dataset in Matlab and then export and define it as the beginning surface of a body in ABAQUS so that I can do a mechanical analysis on it? Is it necessary to export the surface data as mesh in whatever format? The contour residual stress analysis is my primary goal.
Thank you in advance for your response.
A: Hello,
If I’m not mistaken, you are talking about point cloud. First, you should import this dataset to software like CATIA and form your model with this point cloud. Then, import this created model to the ABAQUS and do whatever you want with it.

Shape optimization in Abaqus
Shape optimization is employed towards the conclusion of the design process, when the overall structure of a component is established and only minor adjustments are permitted by relocating surface nodes in specific regions. In shape optimization, the displacements of the surface nodes (design nodes) serve as the design variables. The process commences with a finite element model that requires slight enhancements or with a finite element model derived from a topology optimization. In this training package, first, you will learn the concept of optimization and shape optimization in Abaqus. After that, all required settings to do a shape optimization, such as optimization task and design responses will be fully explained. And in the last lesson, you will learn how to create an optimization process and be familiar with the generated files by the shape optimization process.
Abaqus Topology Optimization
Optimization is a fundamental concept used to enhance the effectiveness and efficiency of systems, designs, and decisions. It finds application in various domains, including industrial processes, finance, and communication networks. In engineering, optimization plays a crucial role in improving the design of systems and structures by maximizing performance and minimizing costs, weight, or other parameters. Structural optimization specifically focuses on designing or modifying structures to meet performance criteria while minimizing or maximizing objectives such as strength, weight, cost, or efficiency. The Abaqus software provides comprehensive structural optimization capabilities, including topology, shape, sizing, and bead optimization. This training package primarily focuses on Abaqus topology optimization. Through the lessons and workshops, you will gain insights into the tips, tricks, and techniques for effectively utilizing topology optimization within the Abaqus software.
Optimization in ABAQUS Analysis
This tutorial teaches how optimize topology of a model in ABAQUS. Structural optimization is an iterative process that helps to improve designs and produce parts and components that are lightweight, strong and long-lasting.
Topology optimization begins with an initial design, which is assumed to be the maximum physical extent of the component, and determines a new material distribution by changing the density and the stiffness of the elements in the initial design while continuing to satisfy the optimization constraints. In this package different workshops to implement topology optimization are used.
Odilon –
This package is worth every penny. It’s rare to find resources that strike a perfect balance between theoretical explanation and practical application, but this one does. The tutorials were clear, the examples were relevant, and the additional resources provided a deeper understanding of BESO topology optimization. It’s an ideal resource for both academic and professional applications. Kudos to the team for creating such a comprehensive and accessible guide!
