The Advanced panel contains subpanels (gravity, springback, trimming, and coarsening) that provide users a means of performing a variety of useful operations in a multi-run setup.

Description |
springback |
Allows you to setup a springback analysis. The springback setup is done using the RADIOSS state file from a previous run. |
trimming |
Allows you to setup a trimming operation. After a stamping simulation, mesh trimming is used to remove unwanted material from the blank. Material may be removed from either the inside or outside of the trim line. Multiple trim lines may be defined. Trimming is completed inside HyperForm. |
Before setting up a springback analysis, you must first import the file containing the part shape, stress and strain history from a previous forming analysis for the blank. Then you must define the section and material properties for the blank component. See the Materials, Section, and Components panels for more information.

There are two different methods available on the Trimming subpanel - 2D and 3D trimming. The 2D trim option allows you to select a trim line, whereby the trim line is computed as the projection of the curve onto the part surface using a single vector direction. The 3D trim option allows you to select a 3D line, whereby the trim line is computed as the closest point projection of the trim curve onto the part surface. The 3D method is very efficient and is superior for parts trimmed at unusual angles or from multiple directions. It is assumed that the trim curve will be defined in very close proximity to the part surface.
For 2D trimming: - For trim part:, click comps and select the blank component to be trimmed. - For trim line:, click line and select the trim line. - All trim lines must be a single combined line. If necessary, you may have to combine lines into a single line. Multiple areas can be trimmed in a single setup by selecting multiple closed loop lines. - For direction, select the direction to sweep the trim line. - For trim option:, select remove element inside or remove element outside. - Click trim. - Click return. For 3D trimming: - For trim part:, click comps and select the blank component to be trimmed. - For trim lines, click line and select the trim line. - All trim lines must be a single combined line. - For reference: select any node on the part which is retained after trimming. Please see the image below which illustrates the functionality of reference node - Click trim. - Click return.
