Researchers at the Centre for Innovative Structures and Materials have developed a series of topology optimisation software packages available for download.
BESO2D is a standalone program for topology optimisation for 2D structures using the latest BESO algorithms. BESO2D comes with a free license and has been introduced in 'Chapter 10 Computer Program BESO2D' by Zuo, Z.H. in the book Evolutionary Topology Optimisation of Continuum Structures: Methods and Applications, Huang, X. and Xie, Y.M. Chichester, England, John Wiley & Sons, Ltd, 2010.
The following Python scripts are implementations of BESO for stiffness optimisation. The Python scripts take advantage of the advanced FEA capacities of the Abaqus software and implement the Abaqus Scripting Interface (ASI). These scripts are published in Zuo ZH, Xie YM (2015). A simple and compact Python code for complex 3D topology optimization. Advances in Engineering Software 85: 1-11. The source codes are explained in detail in this paper.
Python scripts available:
BESO_Basic.py [PY 5KB] (basic version of the Python code)
BESO_Adv_ML.py [PY 5KB] (advanced version with multiple load case capacities)
BESO_Adv_NL.py [PY 5KB] (advanced version with large deformation capacity)
PltResults.py [PY 2KB] (script for automatic display of optimised solution generated by the above scripts)
This is a simple MATLAB code for 2D topological stiffness optimisation. This code has been introduced in Chapter 4 of Evolutionary Topology Optimisation of Continuum Structures: Methods and Applications, by Huang, X. and Xie, Y.M., Chichester, England, John Wiley & Sons, Ltd, 2010.
Ameba is a topology optimisation tool developed by Mike Xie’s team based on the BESO method. It is built on the Rhino Grasshopper platform. Users may, according to design requirements, apply different loading and boundary conditions to the initial design domain. Through an iterative computational process, Ameba will evolve the design domain into various shapes, and eventually reach an organic form that is structurally efficient.
