Geometry Cleanup
Prepare surface geometry for meshing.
When designers create CAD geometry, their priorities are different from those of analysts trying to use the data. A single smooth surface is typically split into smaller patches, each a separate mathematical face. The juncture between two surfaces often contains gaps, overlaps, or other misalignments.
To make the geometry more appropriate for meshing, analysts need to combine a number of faces into a single smooth surface. This allows the elements to be created on the entire region at once, and prevents unnecessary artificial or accidental edges from being present in the final mesh.
