BOUNDARY LINE

 

This function enables the user to create a flat blank mesh using boundary lines. After selecting the function, the user has to select the boundary lines using the functions provided in the SELECT LINE dialog box. Upon completion of line selection, the MESH SIZE dialog box illustrated in the Figure 9.5.2 is displayed.

 

Figure9.5.2 Mesh Size dialog box

 

TOOL RADIUS 每 This input box enables the user to input the smallest concerned tool radius during the forming operation. Normally, it is the profile radius of DIE. The default Tool Radius is set as 1.125 (mm).

 

ELEMENT SIZE 每 This input box enables the user to input the average elements size for the blank mesh. The default Element Size (edge length) is set as 3.0 (mm).

 

CONVERT每 This function enables the user to convert the Tool Radius to the Element Size or vice versa.

 

OK每 This function enables the user to accept the defined parameters and continue the mesh operation. An eta/DYNAFORM QUESTION dialog box as illustrated in Figure 9.5.3 is displayed after the user select OK.

YES 每    Accepts the blank mesh.

 

NO 每     Cancels the operation.

 

REMESH 每 The MESH SIZE dialog box is displayed again. The user can modify the radius/element size.

 

NOTE:

                                                                 1. The selected boundary lines should be lying on the same plane. If not,  blank mesh is generated on the least square plane of the selected line.

                                                                 2. The orientation of the layout of the selected line in the X-Y plane is important for the mesh. The user is recommended to rotate the lines along the Z-axis prior to generating the blank mesh. Please note that different blank mesh is generated according to the different line orientation.
