Abstract: The paper presents an efficient 88 line MATLAB code for topology optimization. It has been developed using the 99 line code presented by Sigmund (Struct Multidisc Optim 21(2):120–127, 2001) as a starting point.

Efficient topology optimization in MATLAB using 88 lines of code The Matlab codes presented in this page are intended for engineering education. Students and newcomers to the field of topology optimization can find the codes here and download them.

gives a brief idea on how to extend the 88 line code to problems involving different boundary conditions, multiple load cases, and passive elements. Furthermore,the inclusion of a Heaviside filter in order to obtain black-and-white solutions is elaborated in more detail. In section 6, the performanceof the 88 line code and its variants is ...
