Isogeometric Topology Optimization Based on Topological Derivatives

Guilherme Henrique Teixeira, Nepomuk Krenn, Peter Gangl +1

Topology optimization is a valuable tool in engineering, facilitating the design of optimized structures. However, topological changes often require a remeshing step, which can bec…

Analysis and structure-preserving approximation of a Cahn-Hilliard-Forchheimer system with solution-dependent mass and volume source

Aaron Brunk, Marvin Fritz

We analyze a coupled Cahn-Hilliard-Forchheimer system featuring concentration-dependent mobility, mass source and convective transport. The velocity field is governed by a generali…

Homotopy methods for higher order shape optimization: A globalized shape-Newton method and Pareto-front tracing

A. Cesarano, B. Endtmayer, P. Gangl

First order shape optimization methods, in general, require a large number of iterations until they reach a locally optimal design. While higher order methods can significantly red…
