When start with product geometry:

1.        From DFE/Preparation/File/Import the product surfaces, create mesh, perform tipping and symmetry;

2.        Create binder and addendum. Exit DFE when finished;

3.        Select DFE/INC Solver, the model created in DFE is already recognized as original die face, shown in green, and recommended draw type is highlighted;

4.        Decide the original side of die face using the pull-down menu;

5.        Create a blank using the functions in Blank Generator;

6.        Define the blank material and thickness;

7.        Define draw beads, if any, and attach to the die (not the binder);

8.        For force-controlled binder, click the active Binder Force field and enter the value (N).

9.        For distance-controlled binder, do nothing to accept the default setup which is 110% of original blank thickness for both tool offset and binder clearance, otherwise click open the Advanced button to define specifically.

10.     Click Apply to position the tools. Animation is available by clicking Preview;

11.     Click Submit Job, option for Gravity loading and/or Spring back if needed; enter refinement levels for Adaptive mesh, then Submit.

12.     When simulation is finished, open Postprocessor and read in the filename_FORM.FAS to view the result.

When start with die face geometry:

1.        From DFE/Preparation/File/Import the die face surfaces, create mesh, tip if necessary. Exit DFE;

2.        Select DFE/INC Solver, define the Draw type and the original side of tools using the two pull-down menus;

3.        Assign geometries to the Binder, Upper or Lower Tool;

4.        Create a blank using the functions in Blank Generator;

5.        Define the blank material and thickness;

6.        Define draw beads, if any, and attach to the die (not the binder);

7.        For force-controlled binder, click the active Binder Force field and enter the value (N);

8.        For distance-controlled binder, do nothing to accept the default setup which is 110% of original blank thickness for both tool offset and binder clearance, otherwise click open the Advanced button to define specifically.

9.        Click Apply to position the tools. Animation is available by clicking Preview;

10.     Click Submit Job, check on Gravity loading and Spring back if needed; enter refinement levels for Adaptive mesh, then Submit;

11.     When simulation is finished, open Postprocessor and read in the filename_FORM.FAS to view the result.

Miscellaneous

The initial mesh on a blank should be as uniform as possible. If the size difference between elements exceeds the ratio of 10:1, job submission will be rejected.

The recommended initial number of elements on a blank is 8000 > n > 1000. For very small parts, n >= 300 is acceptable. The adaptive mesh can be used as an alternative way of controlling the initial number of elements on blank. However, to achieve same simulation resolution in terms of minimum element size on blank, increasing initial mesh density to reduce the levels of refinement usually shortens the simulation time.

When specifying the refinement levels of adaptive mesh, the numerical number entered equals the maximum times that an element can be split during simulation. For example, 3-level means that an element can be split up to 3 times.

In cases that INC Solver aborts right after job submission, open the filename_INFO.OUT with a text editor (WordPad, Notepad, etc.) and check for error message. Modify your setup accordingly and submit again. If the message file contains only the tile statement, very likely the license file is expired. Navigate to the eta/DYNAFORM installation directory and locate the license_info.txt in INC Solver folder, send this file to your administrator for license renewal.
