In the mesh generation and resolution setting section, users can manually define the mesh resolution and the refinement level (0–6). The mesh resolution at level 0 determines the base grid density, where larger values create finer grids and smaller values produce coarser grids. The refinement level specifies how many times the mesh is locally subdivided, with level 0 meaning no refinement and level 6 providing the highest refinement. By combining these two parameters, users can balance mesh quality and computational cost according to their simulation needs. Enabling the Small Feature option allows the software to capture and mesh tiny geometric details more efficiently.
