Topology optimization (TO), a numerical technique to nd the optimal material layout with a given design domain, has attracted interest from researchers in the eld of structural optimization in recent years. For beginners, opensource codes are undoubtedly the best alternative to learning TO, which can elaborate the implementation of a method in detail and easily engage more people to employ and extend the method. In this paper, we present a summary of various open-source codes and related literature on TO methods, including solid isotropic material with penalization (SIMP), evolutionary method, level set method (LSM), moving morphable components/voids (MMC/MMV) methods, multiscale topology optimization method, etc. Simultaneously, we classify the codes into ve levels, from easy to di cult, depending on their di culty, so that beginners can get started and understand the form of code implementation more quickly.

Large cavity structures are widely employed in aerospace engineering, such as thin-walled cylinders, blades and wings. Enhancing performance of aerial vehicles while reducing manufacturing costs and fuel consumption has become a focal point for contemporary researchers. Therefore, this paper aims to investigate the topology optimization of large cavity structures as a means to enhance their performance, safety, and efficiency. By using the variable density method, lightweight design is achieved without compromising structural strength. The optimization model considers both concentrated and distributed loads, and utilizes techniques like sensitivity filtering and projection to obtain a robust optimized configuration. The mechanical properties are checked by comparing the stress distribution and displacement of the unoptimized and optimized structures under the same load. The results confirm that the optimized structures exhibit improved mechanical properties, thus offering key insights for engineering lightweight, high-strength large cavity structures.
