Geometry and meshing

These pages explain how Vanellus turns the domain, components, and sizing controls into one rectilinear computational mesh.

• Geometry and the computational domain describes the fluid region, solid components, coordinates, and voxelized CAD.
• Rectilinear meshing explains how three axis-node arrays define the mesh and why local sizing propagates along those axes.
• CAD voxelization explains how surface triangles become solid cells, including the effects of rotation, resolution, and vertex preservation.
• Mesh resolution and controls explains how sizing requirements, wall resolution, fusing, culling, growth limits, and aspect-ratio correction interact.
