General

Time step size: The default is -1.2e-006, and the interface is illustrated in Figure 8.5.22. The user may click  button to calculate the time step size according to the tube element size and the adaptive level.

Advanced: the advanced parameters for general setup.

Refining meshes

This option is closed by default. The user need to toggle on the Refining meshes option to use this function, as illustrated in Figure 8.5.23.

Figure 8.5.23  Refining meshes

Time steps: The user may set the adaptive time steps. The default is 40.

Minimum element size: Minimum element size to be adapted based on element edge length. The default is 1.

Max. refinement levels: The default is 4.

The user may toggle on the Refining box size to set the working area for refinement. Only the elements within this range will be refined. The default is a square with the bending point as the center and the side length of twice the bending die diameter.

Springback

Springback after bending: This button is not checked by default. The user may check it to implement a springback calculation after bending simulation, as illustrated in Figure 8.5.24.

Edit: Click this button to edit the springback parameters.
