HF-0100: General Introduction
HyperForm, a subset of Manufacturing Solutions, is a finite element based pre- and post-processor for sheet
metal forming. It combines an extremely fast one-step solver and incremental forming solution using Radioss
as the solver. It also integrates well with the LS-DYNA solver for incremental forming simulation. With the
customized geometry manipulation and mesh generation capabilities, HyperForm enables you to build metalforming related finite element models, view their results, and perform data analysis.
HyperForm integrates the functionality of HyperMesh and provides engineers at any stage of product design
with quick, valuable, reliable information, reducing the overall product cyc le. HyperForm's die module enables
engineers to create and analyze conceptual die designs in order to generate an optimized die. Die concepts
can then be read into any CAD system as a starting block for the actual die build. Integrated with HyperView,
HyperForm can export data in the .h3dformat allowing results to be visualized using HyperView Player with
any web browser.
This tutorial introduces HyperForm, as well as many basic concepts and tasks that are needed to get started
with HyperForm, and which serve as pre-requisites for most other HyperForm tutorials. In this tutorial, you
will be introduced to HyperForm from the one-step analysis point of view. The HyperForm interface for
incremental analysis will be described in later tutorials.
This tutorial covers:
Session 1: Fundamental HyperForm user interface
o User Profiles
o Graphics Area
o Using the mouse
o Tool bar menu
o Main menu
o Toggles and switches
o Utility Menu
o The pull-down menus
Session 2: Using the online help

Session 4: The concept of a collector
Collectors store entities, grouping together all the data pertaining to an entity and allowing you to handle the
data as a group. Collectors in HyperForm consist of the Components, Materials and Sections (for
Incremental_Radioss and Incremental_LsDyna analysis) panels.
The component and material collectors in HyperForm have specific data associated with them. In one-step
analysis, the component collector contains thickness data while the material collector holds the YoungsModulus of Elasticity value and other constants.
All entit ies in a HyperForm database are stored in collectors. Based on the analysis type, each collector
may use a dictionary or card image to define the attributes assigned to the collector.
The Collectorspanel allows you to create and update collectors and assign and edit card images or
dictionaries. Before you build a model, create a component collector for storingor organizing different data.
Exercise 2: Understanding collectors and using online help
The Die_Mesh.hmfile from Exercise 1 should still be loaded in HyperForm.
In steps 1 through 6, you will practice changing the visualization of component collectors.
1. In the Model Browser, click on the Mesh icon next to the Partcomponent to turn off the display of
the mesh for that component. Notice the mesh of the Partcomponent is no longer displayed in the
graphics area. The surface of the Partcomponent is still visible.

Session 5: Secondary Menu
The secondary menu contains several stand-alone functions, like calculating the distance between two
points. Accessing the secondary menu interrupts the active main panel and allows you to perform a function
from the secondary panel and then return to the main panel. For example, a user can access the secondary
menu by pressing the function keys, F1 through F12, Shift F1 through shift F12, and more.

using Stamping Directionin the Autotip panel. Use the stamping directionsubpanel to specify the
stamping in an arbitrary direction.
In the Autotippanel, use the vector selector switch to assign a direction. If the stamping direction of
the part is not one of the principal axes, use N1, N2, N3 option and select 2 nodes on the model to
define a direction.
Click set.
Step 4: Selecting the blankholder
Blankholders can be defined as the upper and lower holding surfaces that control metal flow around a shape
to be formed in a draw operation. They supply a restraining force on the material during the pressing
process.
HyperForm allows you to define the blankholder force in two ways: on element and on edge. The correlation
between the magnitude and level of the applied forces is always available. Edge blankholder force applicationallows you to restrain an edge by enabling automatic selection of all nodes between two user-defined nodes
along a free edge of a part.
You can define the blankholder force in two ways: tonnage force or pressure level (high, medium and low).
Note The pressure level is proportional to the area of blank under the blankholder as well as thickness.
A pressure level of 2MPa, 5MPa and 10MPa for a 1mm blank has been chosen as a reference for
Low, Medium, and High (based on practical experience). The tonnage (metric ton unit) is equivalent
to the pressure times the blankholder area normalized/scaled by the thickness (1 metric ton =
9810N).
1. In the OneSteptab, right click on Blankhol ders >New. If desired, you can double click on
Blankholder1 to change the name.
2. Right click on Blankho lder1 >Elements
3. Click elemsand select on plane.

Fr ict ion and Tonnage to change the values.
7. Right click on Pressur e Level: and select Med ium.
Notice that the Tonnagechanges according to the selected pressure level.
Step 5: Creating drawbeads
Modeling the exact drawbead geometry requires a large number of elements, which increases CPU time
dramatically. A practical approach is to use an equivalent drawbead model by representing the drawbead
analytically and providing a constant drawbead restraining force and closure force.

Altair Engineering Manufacturing Solutions 11.0 Tutorials - HyperForm 41
Proprietary Inform ation of Altair Engineer ing
Use the calculatesubpanel to determine the closure and restraining force based on drawbead dimensions.
The restraining force is the value of the force (per unit length) applied by the bead in the plane of the blank
surface. The closure force is the force (per unit length) required in the perpendicular direction to keep the
drawbead closed.
1. From the OneSteptab, right-click on Drawbeads > New >Restrain.
2. Pick two nodes on the part as indicated in the image below to define the drawbeads.

HF-0200: Geometry Cleanup
When designers create CAD geometry, their priorities are different from those of analysts trying to use the
data. A single smooth surface is typically split into smaller patches, each a separate mathematical face.
The juncture between two surfaces often contains gaps, overlaps, or other misalignments.
To make the geometry more appropriate for meshing, analysts need to combine a number of faces into a
single smooth surface. A single, smooth surface not only allows the elements to be created on the entire
region at once, but also prevents unnecessary artificial or accidental edges from being present in the final
mesh.
Sometimes, the gaps, overlaps, and misalignments present when surface data is imported can affect the
mesh quality. By eliminating misalignments and holes, and suppressing boundaries between adjacent
surfaces and unnecessary details, you can automesh across larger, more logical regions of the model and
improve the overall meshing speed and quality.
In this tutorial, you will use a variety of tools to prepare surface geometry for meshing.

solutions are discussed in Exercise 2.
This exercise uses the model file Bpillar_cleanup.hf.
Step 1: Load the model file
1. Click File >Open....
2. Browse to the location \tutorials\mfs\hf\1Stepand select the
Bpillar_cleanup.hffile.
3. Click Open.
Step 2: Review the model in Topology color mode
1. Click View >Toolbars> Visualizat ionto display the Visualization toolbar. The Visualization toolbar will
need the panels displayed also in the Viewmenu.
2. From the toolbar, select Geom etry Color M ode and change to By Topo.
Notice the color of the model is changed and topology definitions are displayed on screen.
3. From the toolbar, click Shaded Geom etry & Surface Edges icon to shade the surfaces on screen.
The model comes in with several geometric problems after importing. You will first review the problems to
have a better understanding of the nature of the model.
In Topologycolor mode, each colorrepresents different topological modes:
Free edge(Red color): The edge is owned by one surface. On a clean model, free edges appear only
along the outer perimeter of the part and internal holes. Free edges that appear between two adjacent
surfaces indicate the existence of a gap between the two surfaces.
Shared edge(Green color): The edge is owned by two adjacent surfaces. When the edges between
two adjacent surfaces are shared (green), there is no gap or overlap between the two surfaces, and they
are geometrically continuous. The automesh utility always places seed nodes along their length and will

produce a continuous mesh without any gaps along that edge. The automesh utility will not construct
any individual elements that cross over a shared edge.
Suppressed edge(Blue color): The edge is owned and shared by two adjacent surfaces but it is ignored
by the automesh utility. They are blue dotted lines by default. Like a shared edge, a suppressed edge
indicates geometric continuity between two surfaces but, unlike a shared edge, the automesh utility will
mesh across a suppressed edge as if were not even there. The automesh utility does not place seednodes along their length and, consequently, individual elements will span across it. By suppressing
undesirable edges you are effectively combining surfaces into larger logical meshable regions.
Non-manifold edge(Yellow color): The edge is owned by three or more surfaces. They typically occur
at "T" intersections between surfaces or when 2 or more duplicate surfaces exist. The automesh utility
always places seed nodes along their length and will produce a continuous mesh without any gaps along
that edge. The automesh utility will not construct any individual elements that cross over a nonmanifold
edge. These edges cannot be suppressed and can sometimes be indication for duplicated geometry.
Step 3: Review and measure the largest pinhole diameter
1. From the toolbar, select the Visualizat ionicon .
