Modeling material transport regulation and traffic jam in neurons using PDE-constrained optimization
Angran Li, Yongjie Jessica Zhang
The intracellular transport process plays an important role in delivering essential materials throughout branched geometries of neurons for their survival and function. Many neurod…
HexDom: Polycube-Based Hexahedral-Dominant Mesh Generation
Yuxuan Yu, Jialei Ginny Liu, Yongjie Jessica Zhang
In this paper, we extend our earlier polycube-based all-hexahedral mesh generation method to hexahedral-dominant mesh generation, and present the HexDom software package. Given the…
Deep learning of material transport in complex neurite networks
Angran Li, Amir Barati Farimani, Yongjie Jessica Zhang
Neurons exhibit complex geometry in their branched networks of neurites which is essential to the function of individual neuron but also brings challenges to transport a wide varie…
Analysis-suitable unstructured T-splines: Multiple extraordinary points per face
Xiaodong Wei, Xin Li, Kuanren Qian +3
Analysis-suitable T-splines (AST-splines) are a promising candidate to achieve a seamless integration between the design and the analysis of thin-walled structures in industrial se…
HexGen and Hex2Spline: Polycube-based Hexahedral Mesh Generation and Spline Modeling for Isogeometric Analysis Applications in LS-DYNA
Yuxuan Yu, Xiaodong Wei, Angran Li +3
In this paper, we present two software packages, HexGen and Hex2Spline, that seamlessly integrate geometry design with isogeometric analysis (IGA) in LS-DYNA. Given a boundary repr…
SimuLearn: Fast and Accurate Simulator to Support Morphing Materials Design and Workflows
Humphrey Yang, Kuanren Qian, Haolin Liu +5
Morphing materials allow us to create new modalities of interaction and fabrication by leveraging dynamic behaviors of materials. Yet, despite the ongoing rapid growth of computati…
Tuned Hybrid Non-Uniform Subdivision Surfaces with Optimal Convergence Rates
Xiaodong Wei, Xin Li, Yongjie Jessica Zhang +1
This paper presents an enhanced version of our previous work, hybrid non-uniform subdivision surfaces [19], to achieve optimal convergence rates in isogeometric analysis. We introd…
The divergence-conforming immersed boundary method: Application to vesicle and capsule dynamics
Hugo Casquero, Carles Bona-Casas, Deepesh Toshniwal +3
We extend the recently introduced divergence-conforming immersed boundary (DCIB) method [1] to fluid-structure interaction (FSI) problems involving closed co-dimension one solids.…
Material characterization and precise finite element analysis of fiber reinforced thermoplastic composites for 4D printing
Yuxuan Yu, Haolin Liu, Kuanren Qian +6
Four-dimensional (4D) printing, a new technology emerged from additive manufacturing (3D printing), is widely known for its capability of programming post-fabrication shape-changin…
Singularity Structure Simplification of Hexahedral Mesh via Weighted Ranking
Gang Xu, Ran Ling, Jessica Zhang +3
In this paper, we propose an improved singularity structure simplification method for hexahedral (hex) meshes using a weighted ranking approach. In previous work, the selection of…
Adaptive FEM-based nonrigid image registration using truncated hierarchical B-splines
Aishwarya Pawar, Yongjie Zhanga, Yue Jia +4
We present an efficient approach of Finite Element Method (FEM)-based nonrigid image registration, in which the spatial transformation is constructed using truncated hierarchical B…
