This function allows the user to simulate the circular grid testing in the actual stamping operation. The program paves the circular grids specified by the user on the deformed mesh. The default size of circular grid is calculated based on the strain of the deformed blank element and is displayed on the deformed blank, as shown in Figure 8.11.1. Refer to Section 8.1 and 8.2 for a description of other buttons.

1.       RADIUS

This parameter is used to define the radius of the circular grid. The default value is calculated according to the element size.

2.       OFFSET

This function defines the distance between landscape and portrait on the circular grid. The default value is calculated according to the element size.

3.       COLOR

This function defines the color of the circular grid. The default color is white.

4.       DEFINE U-V DIRECTION
This function defines the tiling direction of circular grid on the blank. The define process is the same as the one of normal U-V plane definition.

5.       LIST VALUE

This function allows the user to select the circular grid to display the corresponding strain result. It can only be activated after the paving of circular grid. The result of the selected circular grid is displayed in a table in the graphic area, as shown in Figure 8.11.2.
