"Intervals" means the number of mesh edges on a curve (or across a periodic surface). "Interval matching" is the process of assigning intervals that are close to the user-desires, and satisfy the constraints imposed by the various quad and hex meshing algorithms (e.g., equal intervals on opposite sides of a mapped surface). The desired number of intervals (goals) are set on geometric entities by either specifying the interval count or size. "Soft" user-set and auto-set mesh sizes and interval counts are goals. Any hard counts are part of the constraints. The constraints are determined by the meshing schemes, as well as the vertex types (corners) of surfaces, and the edge-types of volumes, and sweep directions. The user may set additional constraints, including upper and lower bounds.
