Parameterization-driven arbitrary Lagrangian-Eulerian method for large-deformation isogeometric fluid-structure interaction
Jingya Li, Ye Ji, Hugo Verhelst +2
Body-fitted arbitrary Lagrangian-Eulerian (ALE) methods provide a sharp representation of the fluid-structure interface but rely on mesh-update strategies that incrementally deform…
Regularity analysis and verification of Coons volume mappings
Yingying Yu, Yashu Liu, Jiaxuan Li +3
The Coons volume provides a classical approach for constructing three-dimensional parametric mappings via boundary surface interpolation and is widely employed in volumetric mesh g…
Efficient thermal simulation in metal additive manufacturing via semi-analytical isogeometric analysis
Yang Yang, Ye Ji, Matthias Möller +1
Thermal modeling of Laser Powder Bed Fusion (LPBF) is challenging due to steep, rapidly moving thermal gradients induced by the laser, which are difficult to resolve accurately wit…
IGA-LBM: Isogeometric lattice Boltzmann method
Ye Ji, Monica Lacatus, Monica LÄcÄtuÅ +1
The lattice Boltzmann method (LBM) offers intrinsic parallelism and simple boundary treatment, but Cartesian lattices approximate curved boundaries by stair steps, causing spurious…
