In this study a description of a new approach, for the generation of multi-block structured computational grids on patient-specific bifurcation geometries is presented. The structured grid generation technique is applied to data obtained by medical imaging examination, resulting in a surface conforming, high quality, multi-block structured grid of the branching geometry. As a case study application a patient specific abdominal aorta bifurcation is selected. For the evaluation of the grid produced by the novel method, a grid convergence study and a comparison between the grid produced by the method and unstructured grids produced by commercial meshing software are carried out.
本研究提出了一种在基于患者的分支几何形状上生成多块结构计算网格的新方法。该结构网格生成技术应用于医学成像检查获得的数据,生成了分支几何形状的表面一致、高质量、多块结构网格。作为案例研究应用,选择了一个特定于患者的腹部主动脉分叉。为了评估新方法生成的网格,进行了网格收敛性研究,并对该方法生成的网格和商业网格生成软件生成的非结构网格进行了比较。
