The grids generated are of Unstructured Mixed element type, suitable for Cell-Centered Solver. For Config 1, Coarse, Medium, and Fine grid levels were generated. For Config 8, only a Fine grid level was generated. A Medium grid level was not generated for Config 8. An Extra fine grid level was not generated for Config1. Grids were not generated for the model with brackets. Config-1 i) Coarse: Number of Nodes: 3,088,347 Number of Cells: 7,695,034 ii) Medium: Number of Nodes: 8,188,411 Number of Cells: 21,903,245 ii) Fine: Number of Nodes: 22,419,724 Number of Cells: 63,305,904 Config-8 i) Medium: Number of Nodes: 23,545,175 Number of Cells: 62,848,368 Additional details related to each grid level are also provided under the corresponding sub-directory.
