TopoCtrl: Post-Optimization Topology Editing Toward Target Structural Characteristics
Hongrui Chen, Dat Quoc Ha, Josephine V. Carstensen +1
Topology optimization can generate high-performance structures, but designers often need to revise the resulting topology in ways that reflect fabrication preferences, structural i…
TopoEdit: Fast Post-Optimization Editing of Topology Optimized Structures
Hongrui Chen, Josephine V. Carstensen, Faez Ahmed
Despite topology optimization producing high-performance structures, late-stage localized revisions remain brittle: direct density-space edits (e.g., warping pixels, inserting hole…
Heterogeneous Metamaterials Design via Multiscale Neural Implicit Representation
Hongrui Chen, Liwei Wang, Levent Burak Kara
Metamaterials are engineered materials composed of specially designed unit cells that exhibit extraordinary properties beyond those of natural materials. Complex engineering tasks…
Multi-scale Topology Optimization using Neural Networks
Hongrui Chen, Xingchen Liu, Levent Burak Kara
A long-standing challenge is designing multi-scale structures with good connectivity between cells while optimizing each cell to reach close to the theoretical performance limit. W…
