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

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.
