Data underlying the publication: A realistic arteriovenous dialysis graft model for hemodynamic simulations

This repository contains processed CFD data required to recreate figures 2 and 3 of the publication: A realistic arteriovenous dialysis graft model for hemodynamic simulations. All data is stored in XDMF/H5 format and can be visualized using scientific visualization software such as paraview (_{https://www.paraview.org/}). The 3D geometries used for this study can be extracted from the result files. <br> The data is structured as follows: <br> * Simulation: Simulation results root folder * Realistic: contains all CFD results of the realistic geometry * flow_metrics: contains all time-averaged derived cfd metrics <br> 3D representations of the wall shear derived metrics are stored in the files below. For the paper only "OSI", "WSS_MAX" and "TAWSS" are used. Other included metrics include the minimal WSS ("WSS_MIN") and the relative residence time ("RRT") * pt01iBlock_wss_metrics.xdmf/h5: (corresponding to the ZF-DB boundary condition in the manuscript) * pt01iZCRCZ_wss_metrics.xdmf/h5: (corresponding to the AVCE-DB boundary condition in the manuscript) * pt01iZCRCZR_wss_metrics.xdmf/h5: (corresponding to the AVCE-DB boundary condition in the manuscript) <br> 3D representations of turbulence metrics are stored in the files below. Root-mean-square magnitude of high frequency velocity perturbations are quantified using the data field "TSI" * turbulenceBlock.xdmf/h5 (corresponding to the ZF-DB boundary condition in the manuscript) * turbulenceZCRCZ.xdmf/h5 (corresponding to the AVCE-DB boundary condition in the manuscript) * turbulenceZCRCZR.xdmf/h5 (corresponding to the AVCE-DB boundary condition in the manuscript) <br> * Idealized: contains all CFD results of the idealized geometry. Same folder structure as Realistic <br> <br> <br>

本仓库包含用于复现论文《用于血流动力学模拟的真实动静脉透析移植物模型》（A realistic arteriovenous dialysis graft model for hemodynamic simulations）中图2与图3所需的经预处理计算流体动力学（Computational Fluid Dynamics, CFD）数据。所有数据均以XDMF/H5格式存储，可通过ParaView（https://www.paraview.org/）等科学可视化软件进行可视化。本研究使用的三维几何模型可从结果文件中提取。
数据组织形式如下：
* **Simulation**：仿真结果根文件夹
* **Realistic**：包含真实几何模型的全部CFD结果
* **flow_metrics**：包含所有经时间平均得到的派生CFD指标。壁面切应力派生指标的三维表示存储于下述文件中。本论文仅使用了"OSI"、"WSS_MAX"与"TAWSS"三项指标，其余包含的指标包括最小壁面切应力（WSS_MIN）与相对停留时间（RRT）：
