The paper presents an a priori procedure to control the element size and shape variation for meshing algorithms governed by
anisotropic sizing specifications. The field of desired element size and shape is represented by a background structure. The
procedure consists in replacing the initial field with a smoothed one that preserves anisotropic features and smaller element sizes.
The smoothness of the resulting field can be controlled by a prescribed threshold value gamma0. Examples are included to show the
application in three dimensional anisotropic adaptive simulation, as well as the effect of gamma0.
