A Unified-Field Monolithic Fictitious Domain-Finite Element Method for Fluid-Structure-Contact Interactions and Applications to Deterministic Lateral Displacement Problems
Cheng Wang, Pengtao Sun, Yumiao Zhang +3
Based upon two overlapped, body-unfitted meshes, a type of unified-field monolithic fictitious domain-finite element method (UFMFD-FEM) is developed in this paper for moving interf…

A Projection-Based Time-Segmented Reduced Order Model for Fluid-Structure Interactions
Qijia Zhai, Shiquan Zhang, Pengtao Sun +1
In this paper, a type of novel projection-based, time-segmented reduced order model (ROM) is proposed for dynamic fluid-structure interaction (FSI) problems based upon the arbitrar…
