02 Outdoor Domain Mesh

Main Components

Cylinder Domain
Define a cylindrical simulation domain for Eddy3D. One cylindrical mesh serves all wind directions; the cylinder side faces switch between inlet and outlet per direction.
Cell Size
Compute the snappyHexMesh refinement level needed to reach a target cell size (each level halves the cell size).
Mesh Settings
Configure mesh refinement, layers, and grading for Eddy3D.
Refinement Region
Add a custom snappyHexMesh refinement region (a box, solid or surface) to a written case's mesh, then re-mesh. Refines the cells inside/near the geometry to the chosen level.
Brep Grid Points
Generate a regular point grid on Brep, surface, or mesh geometry.
