The parameters on the Initial Mesher tab allow you greater control over the initial mesh discretization. This is useful when the default discretization is not satisfactory, either because small features (tightly curved areas, for example) are not discretized finely enough, or when a coarser discretization produces an acceptable result and a faster run time is desired. These parameters are global in effect (affecting all tightly curved areas for example). Mesh discretization can also be controlled by means of mesh constraints on specific bodies, faces, or edges. For more information, see “Mesh Constraints”. For more detailed control over the discretization of the initial mesh, see “Advanced Initial Meshing”.
