Neural enrichment finite element method: A hybrid framework for problems with strong oscillations or interface problems
Shihan Guo, Thomas Richter
We propose a hybrid method, the Neural Enrichment Finite Element Method (NEFEM), designed for problems involving strong oscillations or interface problems with weak discontinuities…

An Unconditionally Stable Explicit Robin-Robin Partitioned Scheme for Fluid-Structure Interaction
Shihan Guo, Ping Lin, Yifan Wang +2
We propose an explicit partitioned (loosely coupled) scheme for fluid structure interaction (FSI) problems, specifically designed to achieve high computational efficiency in modern…

A Fully Parallelizable Loosely Coupled Scheme for Fluid-Poroelastic Structure Interaction Problems
Shihan Guo, Yizhong Sun, Yifan Wang +2
We investigate the fluid-poroelastic structure interaction problem in a moving domain, governed by Navier-Stokes-Biot (NSBiot) system. First, we propose a fully parallelizable, loo…
