•

Surface Forces Available in Cylindrical Coordinate Systems. Cylindrical coordinate systems may now

be applied to Forces applied to surfaces, to facilitate simulations involving cylindrical symmetry.

•

Remote Displacement. Remote Displacement joins the list of supports, allowing users the capability for

applying both a displacement and rotation from an arbitrary remote location in space.

Solution Enhancements

The following solution enhancements have been made at release 9.0:

•

Refinement Depth Control Added to Adaptive Convergence. For adaptive converged solutions, users

can now control the aggressiveness of the mesh refinement.

•

Number of Processors Setting Added to Details View. Users now have the ability to specify the number

of processors to use during solution under the Solution Details View. Previously, the number of processors

could only be set through the Options dialog box.

•

Automatic Time Stepping. Users now have the option to turn automatic time stepping on or off, or to

let the program automatically control it.

Results Enhancements

The following results enhancements have been made at release 9.0:

•

Scoping Results to an Edge/Vertex. Results can now be scoped to multiple edges. A graph showing the

variation of the result along a single scoped edge or contiguous scoped edges is now superimposed over

the result plot and displayed in the Worksheet tab. Prior to this release, the graph was only displayed in

the Worksheet tab.

•

Beam Stress Results. Beam stresses can now be viewed using a new Beam Tool. The types of beam

stresses available include Direct Stress, Minimum Bending Stress, Maximum Bending Stress, Minimum

Combined Stress, and Maximum Combined Stress.

•

Electromagnetic Results. It is now possible to solve for electromagnetic results. The types of results

available are Flux Density, Directional Flux Density, Field Intensity, Directional Field Intensity, Force,

Directional Force, Electric Potential, Inductance, and Flux Linkage.

•

Enhanced Harmonic Results. Users can now request additional contour results and vector plots for

harmonic analyses. Previously, only component stresses, strains and displacements could be displayed.

Now, quantities such as principal stresses and strains, and total displacement can be displayed as well.

•

Error Results for Structural and Thermal Simulations. Error result items are now available that are

based on stresses (for structural simulations) and heat flux (for thermal simulations). Error result items

help identify regions that would benefit from a more refined mesh for producing more accurate results.

•

Vector Display Option. A button added to the Results toolbar allows users to view vector results, which

is extremely useful for viewing Electromagnetic results. A Vector Display toolbar is also available with

various options for controlling vector formats to suit specific viewing applications.

•

Customized Scale Factor for Viewing Deformed Results. The scale factor drop down control in the

Results context toolbar now has a provision for users to enter a customized scale factor as well as using

any of the preset scale factors.

Miscellaneous Enhancements

The following miscellaneous enhancements have been made at release 9.0:

•

Expanded Capabilities for Commands Objects.

1–8

Commands objects have replaced the functionality of Preprocessing and Postprocessing Commands

Objects at this release. ANSYS commands from database files in previous releases that are included

–

in Preprocessing and Postprocessing Commands Objects can be copied and pasted into Commands

objects for use at this release and subsequent releases.

–

Commands objects can now be added to bodies within Geometry objects and Contact Regions

within Contact objects. Prior to this release, they could be used only at the Environment and Solution

object level.

–

Input arguments for ANSYS commands have been incorporated into Commands objects.

–

Commands objects can be renamed to an imported or exported file name. This option is available by

choosing Rename Based on Definition in the context menu that appears from a right mouse button

click on a Commands object.

–

ANSYS plots that result from Commands objects can now be viewed in Workbench. This feature is

useful for viewing results that are available in ANSYS but not in Workbench.

FE Modeler Release Notes

Node Definition Enhancement

Previously, nodes defined with a spherical coordinate system were processed with the Theta and Phi components

in reverse order. Now, these nodes are processed as expected.

Printing and Image Capture Capability

The FE Modeler interface now provides a toolbar that allows you to print or capture and save a displayed image.

These features are available when you are viewing (entities, elements types, etc.) a model using one of the

available selection modes of FEM.

Context Menu Viewing Options

FE Modeler now provides a context menu when you select the right mouse button in the graphics window to

quickly display selection and view options.

DesignXplorer Release Notes

Six Sigma Analysis Enhancements

The following Six Sigma Analysis enhancements have been made at release 9.0:

•

Tables Enhancements. Values can now be added to or deleted from the probability and inverse probab-

ility tables of each parameter, Tables and Charts have been separated in the View Sub-options, and it is

now possible to parameterize statistics for each variable.

•

Charts Enhancements. It is now possible to view different probability axes for cumulative distribution

function plots.

•

Sensitivities Enhancements. Sensitivities plots now distinguish between significant and insignificant

input parameters.

•

Statistical Enhancements. It is possible to parameterize Shannon Entropy and Taguchi Signal-to-Noise

Ratios for use in a robust design study.

Section : DesignXplorer Release Notes

DesignXplorer VT Enhancements

The following DX VT enhancements have been made at release 9.0:

•

Discrete Parameters in DX VT. A DesignXplorer VT solution can now be obtained based on one or more

discrete inputs. This allows the optimization of combinations of discrete variables in order to get an op-

timal solution that will reduce weight or minimize failure in a design.

•

Viewing .rsx Files. DesignXplorer VT can now read .rsx files, which contain all solution information for a

solve using the Variational Technology processor (/SX command) in ANSYS VT. The file can be created in

ANSYS or by a DX VT run in Windows.

• Acceleration and rotational velocity components and magnitudes can be parameterized.

Goal Driven Optimization Enhancements

Goal Driven Optimization now uses a Multi-objective Genetic Algorithm and Pareto ranking to determine the

best possible designs for multi-objective optimization, given parameter goals set in the Goals & Candidates

page.

Min/Max Search Enhancements

Previously, a Min/Max search was performed automatically at the end of the solution process. This automatic

search has been removed and it is now possible to perform the search whenever desired. The Min/Max search

will examine the entire output parameter space to approximate the minimum and maximum of each output

parameter.

New Options for DesignXplorer and DX VT

The following settings have been added to the Options dialog box that are applicable to DesignXplorer and DX

VT:

•

Automatic Design Points: Specifies a Central Composite Design type for helping to improve response

surface fits for DOE studies.

•

Number of Gridlines: Enhances the viewing of 2-D/3-D Response Surface charts by controlling the

number of points used by the continuous input parameter axes.

•

Color Usage: Controls color quality and chart rendering speed for tradeoff charts.

•

Maximum Mesh Distortion: Controls the overall mesh quality for DX VT.

•

Significance Level: Sets the relative significance of input variables.

•

Correlation Coefficient Calculation Type: Specifies the method for calculating correlation coefficients.

•

Parameter Naming Convention: Controls what parameters will be named.

Robust Design

DesignXplorer now supports Robust Design studies, which combine Optimization and Six Sigma Analysis to

optimize Six Sigma Analysis results to minimize the probability of failure.
