History-Compatible Energy-Stable Finite Element Schemes for Variable-Density Cahn--Hilliard--Navier--Stokes Flows on Evolving Meshes
Wenbin Wang, Yunqing Huang, Yin Yang +1
We consider variable-density Cahn--Hilliard--Navier--Stokes (CHNS) discretizations on finite element meshes that may change between accepted time levels through fixed-topology moti…

A Trace--Logarithmic Variational Functional for Equidistribution and Alignment in Moving Mesh Adaptation
Wenbin Wang, Yunqing Huang, Huayi Wei
Existing variational mesh functionals often require an empirical equidistribution--alignment weight or use a strongly nonlinear density. We propose a calibrated trace--logarithmic…

FEALPy: A Cross-platform Intelligent Numerical Simulation Engine
Yangyang Zheng, Huayi Wei, Yunqing Huang +5
In resent years, the software ecosystem for numerical simulation still remains fragmented, with different algorithms and discretization methods often implemented in isolation, each…
