What’s
New in ANSYS Workbench including DesignSpace 8.0 and ANSYS 8.0 in
Workbench environment?
General
DesignSimulation News:
These features are available in DesignSpace and all ANSYS licenses in
Workbench Environment
Highlighting
Contact Regions
When a contact region is selected in the tree,
the corresponding bodies along with source and target entities are
graphically highlighted. The highlighting is accomplished internally by
changing the Transparency setting of the highlighted bodies so as to
subdue parts that are not involved with the selected contact region. The
two Transparency settings can be changed in the Control Panel. The
highlighting feature may be disabled through a context menu.
Identifying
Contact Regions from Body Selection
After selecting one or more vertices, edges, faces, or bodies, users can
now identify all contact regions associated with the bodies by choosing
Contacts for Selected Bodies from the context menu (right mouse click in
the Geometry window). The associated contact regions are displayed
graphically and selected in the tree.
Geometry
Scale Ruler
A scale ruler has been added to the Geometry window that provides an
approximate scale of the model, similar to a scale on a geographic map.
The scale ruler is a useful tool when setting mesh sizes. Like the triad,
the ruler can be toggled on or off from the View menu or from the Standard
Toolbar.
Box
Select
The Selection Toolbar has been
modified at release 8.0 to include a Select Mode button that allows you to
select items designated by the Selection Filters through the Single Select
or Box Select dropdown menu options. The Box Select filters allow you to
choose all filtered items by dragging a selection box. There are two types
of selections based on the dragging direction. When the dragging is from
left to right, items completely enclosed in the box are selected. When the
dragging is from the right to the left, items completely and partially
enclosed in the box are selected. Note the difference in the hash marks
along the edges of the box to help you determine which box selection type
will be performed.
Show
Undeformed Model As Translucent
The Edges drop down menu in the Result toolbar now includes the Show
Undeformed Model option that allows contour results viewing of the
deformed model highlighted against a subdued view of the undeformed model.
This feature is particularly useful for viewing results on the interior of
a body while simultaneously viewing the undeformed version as a reference.
This feature also works with section and iso plots.
Large
Model Improvements
Several improvements have been made to the
support for large models, among them being increased speed, applying
loads, solving, memory usage, meshing, and graphics processing.
Compression Only
Support
The capability of the Pinned Cylinder Support has been expanded to include preventing one or more surfaces from moving or deforming. Its name has been changed to Compression Only Support and it is accessible in the same way as the Pinned Cylinder Support was in previous releases except that now it can be applied to non-cylindrical surfaces as well.
Simulation
Wizard Editor
The Simulation Wizard Editor, a standalone Windows application that allows
users to customize wizards, is now accessible from the Tools menu in
Design Simulation.
Physics
Type Filters
Physics Type filters have been added in the Details View of the Model
level. These filters enable toolbar and menu items in the Environment and
Solution levels that apply only to the chosen physics type. At release
8.0, Structural and Thermal physics types have been added.
New
features in Workbench Environment with ANSYS Professional license
Surface Body Contact
Prior to release 8.0, contact could only be
scoped to faces of solid bodies. Now, contact can be scoped to surface
body edges and faces as well. The new contact features are useful for
joining together surface body assemblies, solid-surface assemblies, or to
model edge welds on solid assemblies.
Specifying Pinball
Region
An advanced contact option has been added that allows users to specify the contact search radius, commonly referred to as the pinball region. Whereas the default Program Controlled setting is applicable in most situations, a user input setting is applicable in cases where the separation between parts is greater than what the program detects as a condition where the parts are in contact. Examples are large gaps that could result from modeling the midsurface of a shell (depending on the shell thickness), or a large deflection problem where a considerable pinball region is required because of possibly large amounts of penetration.
Meshing
With Generic Elements
The mesh can now be exported to ANSYS using generic elements
that encode only shape and connectivity information. Once in ANSYS, users
can replace the generic elements by others appropriate to the analyses
performed in ANSYS. This is of value to users who wish to take advantage
of the meshing capability afforded by Design Simulation to perform
analyses that are only supported in ANSYS. This feature is accessible by
creating an ANSYS input file using Tools> Write ANSYS Input File....
Generic elements will be exported whenever the Analysis Type is Unknown in
the Solution Details View.
New
features in Workbench Environment with ANSYS Structural or higher license
Pretension
Bolt Load
A pretension bolt load has been added to the available list of structural
loads, for use in structural and thermal-stress analyses. This load
applies a pretension to a cylindrical surface, typically to model a bolt
under pretension. As input only pre-tension force value or initial
displacement adjustment needed to input. The analysis requires two load
steps. Preloads are applied in load step one. Pretension loads will become
"locked" in load step two and the working loads will be applied.
New Workbench Product Relesead:
Hex Dominant Meshing
A Hex Dominant option has been added to the Element Shape Control, allowing an unstructured hex mesh to be applied to solid bodies. This functionality is enabled by the Advanced Meshing Module license that is purchased separately.Hex dominant meshing offers benefits mainly when meshing bodies with large amounts of interior volume, or bodies that transition from sweepable parts. It offers minimal benefits when meshing thin complex parts (like a cellular phone case) or when meshing sweepable bodies that are decomposed to multiple sweepable bodies.To assist users in determining if hex dominant meshing is applicable to specific situations, when the Hex Dominant option is applied, Design Simulation internally calculates a normalized volume to surface area ratio on the bodies. If the ratio is less than 2 for at least one body, a warning message states that a low percentage of hex elements or poorly shaped hex elements may result. The message includes suggestions for applying alternative meshing schemes.
