Level set-fitted polytopal meshes with application to structural topology optimization
Nicola Ferro, Stefano Micheletti, Nicola Parolini +3
We propose a method to modify a polygonal mesh in order to fit the zero-isoline of a level set function by extending a standard body-fitted strategy to a tessellation with arbitrar…

Advanced Modeling of Rectangular Waveguide Devices with Smooth Profiles by Hierarchical Model Reduction
Gines Garcia-Contreras, Juan Corcoles, Jorge A. Ruiz-Cruz +4
We present a new method for the analysis of smoothly varying tapers, transitions and filters in rectangular waveguides. With this aim, we apply a Hierarchical Model (HiMod) reducti…

Enhancing level set-based topology optimization with anisotropic graded meshes
Davide Cortellessa, Nicola Ferro, Simona Perotto +1
We propose a new algorithm for the design of topologically optimized lightweight structures, under a minimum compliance requirement. The new process enhances a standard level set f…
