DRAWBEAD BOX
The DEFINE BOX function is used to define a specific box-shaped volume around the drawbead. The box contains the drawbead nodes and elements between the bead and the outer edge of the blank. It is implemented to limit the size of the master surface for the drawbead contact. The BOX SIZE is the linear distance between the drawbead line and the surfaces of box. The default size of the drawbead box is 200. The user can key in the size of the box following by clicking the APPLY to modify the size of drawbead box.
NOTE: It is highly recommended to define a box around the drawbead to limit the size of the master surface (Blank) considered for the drawbead. It will substantially reduce cost and memory requirements for stamping simulation.
