BESO for 2D

A basic topology optimization program using soft-kill BESO technique.

Introduction

The program was initially written in Jupyter-lab and merged to a single .py file. All the necessary parameters can be modified in 1172-1250 lines.

Predefined Load Conditions

• Half beam
• Beam
• Cantilever
• Michell structure with two simple supports
• Michell structure with one simple support and one roller

Predefine Finite Element solvers

• Numpy solver (Slow, unefficient but formidable)
• Cvxopt solver (Recommended)

Necessary Packages

• NumPy
• Matplotlib
• Scipy
• Numpy
• CVXOPT
