VASTO: Simultaneous recovery of vascular geometry and blood flow via differentiable topology optimization
Pramod Thombre, Rahul Kumar Padhy, Roshan M. D'Souza +1
Computed Tomography Angiography (CTA) is widely used to reconstruct vascular geometry from projection measurements, with conventional approaches such as Filtered Back-Projection (F…
MOTO: Topology Optimization for Large Deformations via an Implicit Material Point Method
Rahul Kumar Padhy, Aaditya Chandrasekhar, Krishnan Suresh
The Finite element method (FEM) has long served as the computational backbone for topology optimization (TO). However, for designing structures undergoing large deformations, conve…
PILL-CoDe: Inverse Design of Polypills via Automatic Differentiation for Prescribed Drug-Release Kinetics
Rahul Kumar Padhy, Aaditya Chandrasekhar, Amir M. Mirzendehdel
Polypills are single oral dosage forms that combine multiple active pharmaceutical ingredients and excipients, enabling fixed-dose combination therapies, coordinated multi-phase re…
TOMATOES: Topology and Material Optimization for Latent Heat Thermal Energy Storage Devices
Rahul Kumar Padhy, Krishnan Suresh, Aaditya Chandrasekhar
Latent heat thermal energy storage (LHTES) systems are compelling candidates for energy storage, primarily owing to their high storage density. Improving their performance is cruci…
TOFLUX: A Differentiable Topology Optimization Framework for Multiphysics Fluidic Problems
Rahul Kumar Padhy, Krishnan Suresh, Aaditya Chandrasekhar
Topology Optimization (TO) holds the promise of designing next-generation compact and efficient fluidic devices. However, the inherent complexity of fluid-based TO systems, charact…
VoroTO: Multiscale Topology Optimization of Voronoi Structures using Surrogate Neural Networks
Rahul Kumar Padhy, Krishnan Suresh, Aaditya Chandrasekhar
