16807 thoracolumbar osteo-ligamentous spine virtual FE input files (part-10: model 9289 to 10289)

16807 thoracolumbar osteo-ligamentous spine virtual FE input files (part-10: model 9289 to 10289) 16807 FE input files representing thoracolumbar spine hexahedral models, including point coordinates. To reduce the size of shared virtual finite element (FE) models, only point coordinates are shared here. The mean FE input file "Mean_Model (Template).inp" is also shared, which includes point coordinates, mesh connectivity IDs, and element sets. To generate virtual FE input files for any of the 16807 models, the corresponding shared point coordinates can be replaced into the mean FE input file (Mean_Model (Template).inp). Mesh connectivity IDs, and element sets are the same in all of FE input files. Mean FE input file includes vertebras and IVDs hexahedral meshes; pelvis, sacrum, and the femoral head triangulated meshes; and ligaments. Each point coordinate file is almost 39MB. An excel file: "Descriptive_List (16807_FE_virtual_models).xlsx" reporting measured spinopelvic parameters for 16807 virtual FE hexahedral models. The Excel file includes measured spinopelvic parameters (PI, PT, SS, LL, LL-PI, GT, RPV, RLL, LDI, RSA, TPA, and scoliosis cobb angle), GAP and IVD centric thickness for FE virtual cohort. Model ID in the excel file is correspondent to the model’s name. One video file: "how_to_replace_point_coordinates.mp4". It shows how you can replace point coordinates here to the mean FE input file "Mean_Model (Template).inp" in order to generate specific FE input file. Notes: 1- Model number in "Descriptive_List (16807_FE_virtual_models).xlsx" is correspondent to the same model number in the 16807 stereolithography (stl) files (.stl extension) representing the virtual thoracolumbar spine triangulated meshes (DOI: 10.5281/zenodo.7715658; stl.part01.rar to stl.part09.rar). 2-These point coordinates are sampled by combining the first 5 shape modes of the morphed-mesh statistical shape model in which each shape mode is discretized into 7 standard deviations: -3, -2, -1, 0, 1, 2, 3. 3- Generated FE inp files can be opened by Abaqus 2019 and later. Any other FE software which supports .inp extension also can open the files.

16807个胸腰椎骨-韧带脊柱虚拟有限元（Finite Element, FE）输入文件（第10部分：模型9289至10289）：共包含16807个代表胸腰椎脊柱六面体网格模型的有限元输入文件，其中包含节点坐标。为缩减共享虚拟有限元模型的体积，本次仅共享节点坐标。同时共享了平均有限元输入文件"Mean_Model (Template).inp"，该文件包含节点坐标、网格连接ID以及单元集。若要生成16807个模型中任意一个的虚拟有限元输入文件，可将对应共享节点坐标替换至该平均有限元输入文件（"Mean_Model (Template).inp"）中。所有有限元输入文件的网格连接ID与单元集均保持一致。
平均有限元输入文件包含椎体与椎间盘（Intervertebral Disc, IVD）的六面体网格、骨盆、骶骨及股骨头的三角网格，以及韧带结构。每个节点坐标文件的大小约为39MB。
另有Excel文件"Descriptive_List (16807_FE_virtual_models).xlsx"，该文件记录了16807个虚拟有限元六面体网格模型的实测脊柱骨盆参数。该Excel文件包含的参数有：实测脊柱骨盆参数（骨盆入射角PI、骨盆倾斜角PT、骶骨倾斜角SS、腰椎前凸LL、LL-PI、骨盆倾斜GT、椎体旋转RPV、腰椎旋转RLL、腰椎间盘退变指数LDI、骶骨旋转角RSA、胸椎前凸角TPA，以及脊柱侧凸Cobb角）、GAP值与椎间盘中心厚度，用于该虚拟有限元队列。文件中的模型ID与对应模型名称一一匹配。
另有视频文件"how_to_replace_point_coordinates.mp4"，该视频演示了如何将节点坐标替换至平均有限元输入文件"Mean_Model (Template).inp"中，以生成特定的有限元输入文件。
备注：
1. "Descriptive_List (16807_FE_virtual_models).xlsx"中的模型编号，与代表胸腰椎脊柱虚拟三角网格模型的16807个立体光刻（Stereolithography, STL）文件（扩展名为.stl，DOI: 10.5281/zenodo.7715658；压缩包为stl.part01.rar至stl.part09.rar）中的模型编号一一对应。
2. 本次共享的节点坐标通过结合变形网格统计形状模型的前5个形状模态采样得到，每个形状模态被离散为7个标准差区间：-3、-2、-1、0、1、2、3。
3. 生成的有限元inp文件可使用Abaqus 2019及更高版本打开，任何支持.inp格式的其他有限元软件也可读取该类文件。
