More Hot Keys

New set of hot keys (short cuts) for frequently repeated operations


• Improved visualization controls for modeling and topology verifications

• Available through View options or directly from the Toolbar

Additional Visualization Controls

Vertex DisplayEdge Direction Display


Single/Box selection toggle

• RMB + LMB combination to easily toggle between the two selection modes

Auto Freeze during slicing

• Slice feature and Slice Material operations are now available for all bodies

– Both active and frozen

• Active bodies involved in the slice are changed to frozen state automatically

Additional Usability Enhancements

Active Bodies

Bodies involved in the slice

are changed to a frozen

state automatically


Improved Named Selection transfer between ANSYS DesignModeler and other ANSYS Workbench applications

Improved Error handling

• Attach failures

• Share topology failures

A new export property inside

DesignModeler to control

named selection transfer to

other workbench applications

Improved error handling to

provide appropriate error and

warnings in case of failures

Improved Named Selection Transfer and Error Handling


• Selection tolerance

– Tolerance is used to detect face pairs in case of imperfect offsets

– Selecting an undetected pair manually provides feedback on tolerance value required, which can be used for automated selection

– Default value is set to zero

• Trimming and other cleanup improvements

Mid Surfacing Improvements

Without selection

toleranceAll the pairs detected

successfully with Selection

tolerance

Selection tolerance value

is suggested to user


• A new option to import and create Shaft geometry

• Reads input from a text file and automatically creates line bodies with specified cross-sections

Rotor Shaft Feature

Line bodies for rotor

shafts

Cross sections are

assigned automatically

Input data in a text file


• Bi-directional geometry transfer between Ansoft products and Workbench applications for multi-physics simulations (DesignModeler/Mechanical/Meshing)

Improved Interoperability with Ansoft Products


Several new readers to provide two types of interfaces for all major CAD systems for improved productivity and flexibility

• Associative Interfaces

– Associative, parametric and Bi-directional

• Readers

– Native file readers for users without live CAD access

A new DWG Reader for AutoCAD

Improved model processing for faster and targeted updates

Improved CAD Interoperability

ANSYS 14.0 Meshing Advances


Rapid & Robust Meshing

Top on the list of challenges

engineering companies are facing is

shortened product development

schedules while at the same time the

product designs themselves are

becoming increasingly complex.

Meshing of these designs introduce

challenges in terms of speed,

robustness and accuracy.

Persistence

• Record and replay sequence of meshing steps

Flexibility

• Adv. Front surface meshing

• Separate min sizefor curvature & proximity

Selective Control


Virtual Topologies (VT) enabling improved automation, flexibility, and usability:

• More interactive usage through direct graphics interaction rather than tree objects

• Ability to run “Auto VT” on selected edges, faces or bodies

• Clustering of faces/edges

• Create hard vertex

• Face splits

• Improved meshing performance w/VTs

Cluster 1

Cluster 2

2 Virtual Faces created.

1 for each cluster.

Virtual Topologies


Flexibility: Allows user to get mapped or swept mesh in easier fashion

Virtual Topologies


Virtual Topologies


Mesh connections now work at part level:

• Post mesh connections by default (pre option still exists)

• Base part mesh stored to allow for quick changes

Mesh Connections


Local connection changes or mesh changes only affect local area:

Mesh Connections


Can mix and match mesh methods with mesh connections, and or use selective meshing:

Support for default and/or uniform quad/tri

Uniform quad/tri

Default quad/tri

Mesh connections


Better quad smoothing:

• Improved laplacian smoothing

• More ruled mesh on rectangles, etc.

Shell Meshing Improvements

13.0 Default quad/tri

14.0 Default quad/tri

Example has ribs attached that

are hidden


MultiZone improvements

• Imprinting

– Through bodies

– Through long stretches of connected side faces
