Mesh density is usually controlled by the intervals, i.e. the number of mesh edges, specified on curves. Intervals are set on a curve by either specifying the interval count directly or by specifying a desired size for each interval. Intervals and interval size can be specified for curves individually, or indirectly by specifying intervals for higher order geometry containing those curves. Because of interval constraints imposed by various meshing algorithms in CUBIT, the assignment of intervals to curves is not completely arbitrary. For this reason, a global interval match must be performed prior to meshing one or more surfaces or volumes.
