A novel nonsmooth approach for flexible multibody systems with contact and friction in 3D space

N Song, H Peng, Z Kan, B Chen - Nonlinear Dynamics, 2020 - Springer
For computational multibody system dynamics, contact and friction problems are very
complex and important problems. Therefore, this paper proposes a novel nonsmooth …

CT Miller, K Bruning, CL Talbot… - Water Resources …, 2019 - Wiley Online Library
A closure relation for capillary pressure plays an important role in the formulation of both
traditional and evolving models of two‐fluid‐phase flow in porous medium systems. We …

A nonlinear elimination preconditioned inexact Newton method for blood flow problems in human artery with stenosis

L Luo, WS Shiu, R Chen, XC Cai - Journal of Computational Physics, 2019 - Elsevier
Simulation of blood flows in the human artery is a promising tool for understanding the
hemodynamics. The blood flow is often smooth in a healthy artery, but may become locally …

An efficient bound-preserving and energy stable algorithm for compressible gas flow in porous media

J Kou, X Wang, H Chen, S Sun - Journal of Computational Physics, 2023 - Elsevier
Due to the great significance of the natural gas and shale gas, it is becoming increasingly
important to simulate compressible gas flow in porous media. The model obeys an energy …

Nonlinear preconditioning strategies for two-phase flows in porous media discretized by a fully implicit discontinuous Galerkin method

L Luo, XC Cai, DE Keyes - SIAM Journal on Scientific Computing, 2021 - SIAM
We consider numerical simulation of two-phase flows in porous media using implicit
methods. Because of the complex features involving heterogeneous permeability and …
