STL files of the bridge results from the paper: Length scale control for high resolution three dimensional level set based topology optimization, SMO, 2021.

Abstract:
This work considers an efficient approach for length scale control in high resolution three-dimensional level set based topology optimization. A contrast parameter based cut element method is employed to ensure a crisp interface representation while working on fixed background hexahedral meshes. This enables the use of efficient multigrid preconditioned Krylov methods in massively parallelized computations. The minimum length scale is controlled using a projection filter without the need for beta-continuation. The capabilities of the proposed approach is demonstrated on several numerical examples using more than 62 million hexahedral elements.
