Top3d is a free MATLAB® program that solves topology optimization problem in 3D. The program is:
- compact without sacrificing readability,
- easy-to-use without losing complexity, and
- multi-functional without programming immensity.
Installation
Save the program top3d.m (8 kB) and start MATLAB in the same directory. The program can be promoted by line:
top3d(30, 10, 2, 0.5, 3.0, 1.2)
A quick start guide is available here.
More step-by-step tutorials are also available here.
