mytopopt's Introduction

MyTopOpt

This is a simple topology optimization program completed in C++, while using python to complete the diagram, the project is completed in the linux architecture using VScode IDE.

Getting Started

git clone https://github.com/HajerZhang/MyTopOpt.git

Prerequisites

What things you need to install the software and how to install them

python3 with numpy, matplotlib， PIL，tqdm

(maybe future will use eigen3)

Installation

How to use

Windows & Linux:

make

Debug mode:

make debug

How to run:

./main.exe

How to plot the result:

python3 plot.py

Usage example

Topology optimization of 2D MBB beam:

Gif of the process:

The final result:

Deployment

Install the python3 and the required packages, then run the plot.py to create the topology optimization result in file './plot'.
