| 1 | OpenIFEM:A High Performance Modular Open-Source Software of the Immersed Finite Element Method for Fluid-Structure Interactions显示文摘We present a high performance modularly-built open-source software-OpenIFEM.OpenIFEM is a C++implementation of the modified immersed finite element method(mIFEM)to solve fluid-structure interaction(FSI)problems.This software is modularly built to perform multiple tasks including fluid dynamics(incompressible and slightly compressible fluid models),linear and nonlinear solid mechanics,and fully coupled fluid-structure interactions.Most of open-source software packages are restricted to certain discretization methods;some are under-tested,under-documented,and lack modularity as well as extensibility.OpenIFEM is designed and built to include a set of generic classes for users to adapt so that any fluid and solid solvers can be coupled through the FSI algorithm.In addition,the package utilizes well-developed and tested libraries.It also comes with standard test cases that serve as software and algorithm validation.The software can be built on cross-platform,i.e.,Linux,Windows,and Mac OS,using CMake.Efficient parallelization is also implemented for high-performance computing for large-sized problems.OpenIFEM is documented using Doxygen and publicly available to download on GitHub.It is expected to benefit the future development of FSI algorithms and be applied to a variety of FSI applications. | Jie Cheng Feimi Yu Lucy T.Zhang | 2019 | Computer Modeling in Engineering & Sciences2019，，4： | 2 |
| 2 | Simulation of vessel tissue remodeling with residual stress:an application to in-stent restenosis显示文摘We present a numerical procedure to model the artery wall remodeling stimulated by stenting considering varying degree of residual stresses.This framework sets up biological remodeling with the existence of residual stress.Previous studies suggest that the residual stress originates from the growth and remodeling of the premature tissue.Meanwhile,it is known that tissue remodeling can happen under mechanical loading.However,none of the existing research studies the impact of residual stress on the mechanical-driven growth of biomaterials.To fill this gap,we build a numerical framework that couples the residual stress with a growth model,and examine its impact on tissue remodeling.The proposed approach is applied to in-stent restenosis,where the tissue remodeling process is modeled with finite element method,and the residual stress is generated geometrically using open angle method.The result shows that residual stress reverses the radial distribution of stress concentration,which is ameliorated by tissue remodeling.The thickening of vessel wall tends to increase with residual stress,which links to more severe in-stent restenosis.The results demonstrate the important interplay between residual stress and tissue remodeling.The findings suggest that residual stress should be considered in the future simulation of tissue remodeling. | Jie Cheng Lucy T.Zhang | 2019 | International Journal of Smart and Nano Materials2019，10，1： | 1 |
