STL Cylinder Geometries for HemeLB Simulations

These cylinder geometries are used to verify models in HemeLB. They have cross-sections approximated by 128 edges and feature radius-to-length ratios of 1:10 for cylinder.stl and cylinder_deg20.stl, and 1:20 for cylinder_extended.stl. The cylinder.stl geometry is aligned along the z-axis, while cylinder_deg20.stl is a 20-degree rotation of cylinder.stl. Provided in STL format, these geometries are defined with arbitrary units. Users can create the simulation domain for HemeLB in GMY format from this geometry by using the voxeliser available here.

此类圆柱几何模型用于验证HemeLB中的模拟模型。其横截面采用128条边近似拟合，其中cylinder.stl与cylinder_deg20.stl的半径-长度比为1:10，cylinder_extended.stl的半径-长度比则为1:20。cylinder.stl几何模型沿z轴对齐，而cylinder_deg20.stl是cylinder.stl经20度旋转后的版本。此类几何文件以STL格式提供，采用任意单位定义。用户可通过此处提供的体素化工具，基于该几何模型生成适配HemeLB的GMY格式模拟计算域。
