StepCAD: Mesh-to-CAD Code Generation via LLM Policy and Geometry-Guided Search
Ghadi Nehme, Faez Ahmed
Recovering executable CAD programs from 3D meshes is challenging due to the compositional nature of CAD construction and the interaction between discrete modeling choices and conti…
MiDShip: Multimodal Dataset of Ship Cargo Hold Structures for Engineering Design
Noah J. Bagazinski, Md. Ferdous Alam, Jaya Manideep Rebbagondla +1
Ship structures govern vessel strength, safety, and manufacturability, but their design must satisfy hundreds of classification society requirements, making the process complex and…
CADFit: Precise Mesh-to-CAD Program Generation with Hybrid Optimization
Ghadi Nehme, Eamon Whalen, Faez Ahmed
Despite recent progress, recovering parametric CAD construction sequences from geometric input, such as meshes or point clouds, is a key challenge for design and manufacturing, as…
TO-Agents: A Multi-Agent AI Framework for Subjective Preference-Guided Topology Optimization
Isabella A. Stewart, Hongrui Chen, Faez Ahmed
Topology optimization can generate efficient structures, but designers often must manually translate qualitative intent, such as desired visual style, product experience, or manufa…
FLARE: A Data-Efficient Surrogate for Predicting Displacement Fields in Directed Energy Deposition
Kittipong Thiamchaiboonthawee, Ghadi Nehme, Ram Mohan Telikicherla +5
Directed energy deposition (DED) produces complex thermo-mechanical responses that can lead to distortion and reduced dimensional accuracy of a manufactured part. Thermo-mechanical…
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…
BlendedNet++: A dataset and benchmark for field-resolved aerodynamics and inverse design of blended wing body aircraft
Nicholas Sung, Steven Spreizer, Mohamed Elrefaie +2
The conceptual design of Blended Wing Body (BWB) aircraft is often constrained by the high computational cost of resolving complex aerodynamics over a high-dimensional design space…
GIT-BO: High-Dimensional Bayesian Optimization with Tabular Foundation Models
Rosen Ting-Ying Yu, Cyril Picard, Faez Ahmed
Bayesian optimization (BO) struggles in high dimensions, where Gaussian-process surrogates demand heavy retraining and brittle assumptions, slowing progress on real engineering and…
C-ShipGen: A Conditional Guided Diffusion Model for Parametric Ship Hull Design
Noah J. Bagazinski, Faez Ahmed
Ship design is a complex design process that may take a team of naval architects many years to complete. Improving the ship design process can lead to significant cost savings, whi…
ShipGen: A Diffusion Model for Parametric Ship Hull Generation with Multiple Objectives and Constraints
Noah J. Bagazinski, Faez Ahmed
Ship design is a years-long process that requires balancing complex design trade-offs to create a ship that is efficient and effective. Finding new ways to improve the ship design…
