  AFDEX 3D is utilizing tetrahedral finite elements because of their generality in remeshing. You know two small elements near plastic region can cause frequent remeshings which deteriorate solution accuracy due to artificial change of geometry of material and excessive smoothing of state variables including strain, etc.
  A good mesh system in 3D space can thus be defined as the one that is composed of minimized number of elements and describes the characteristic lines and surfaces on the material sufficiently enough to describe the die-material contact. 
  These figures show some typical applications of mesh density control function to an automatic multi-stage cold forging process of yoke, a fine blanking process and a cold forging process.
