An Advection-Diffusion based Filter for Machinable Designs in Topology Optimization - STL files

STL files of the structures from 3D examples in "An Advection-Diffusion based Filter for Machinable Designs in Topology Optimization".

The bracket designs contain the optimized part of the designs only. Use the included passive pin and passive rings files to obtain the full model.

Abstract:
This paper introduces a simple formulation for topology optimization problems ensuring manufacturability by machining. The method distinguishes itself from existing methods by using the advection-diffusion equation with Robin boundary conditions to perform a filtering of the design variables. Furthermore, the approach is easy to implement on unstructured meshes and in a distributed memory setting. Finally, the proposed approach can be performed with few to no continuation steps in any system parameters. Applications are demonstrated with topology optimization on unstructured meshes with up to 64 million elements and up to 29 milling tool directions.
