ANSYS 13.0

Geometry and Meshing

• Feature release driven by customer requests• Focused on providing value for:

– More automated and flexible CFD modeling/meshing process


– More automated and flexible Beams & Shells modeling/meshing process

– More robust hex modeling/meshing– Improved performance

13.0 Geometry Enhancements

Automatic Surface Extension

• Improved shell modeling:

– Extension groups are identified based on user specified gap

– Initial value for the


– Initial value for the gap is prefilled

– Visual feedback for selecting gap

– View and edit options similar to repair tools

Joints and Mid-Surface

Improvements

• Improved Mid-Surfacing– Surface thickness can be assigned at the body level or at the face

level– Thickness assignment for multiple faces in a single step


• Improved joint handling– Joint feature now allows selection

of both surface and lines– Easy to form shared topology

between line and surface bodies

Visualization Tool to Display

Connectivity

• Edge color based on number of faces sharedFree – 0 face - BlueBlueSingle – 1 face – RedRed


Double – 2 faces – BlackTriple – 3 faces – PinkPinkMultiple – 4 faces – YellowYellow

• Color choices can be customized

Easy Visualization of Edge

Connectivity

• Thickness control for specific edge types

• View options to control display of specific types


Thick MultipleDisplay only Single edges

Improved Selection

• Both sides highlighting during selection– Easy to view selection

in complex models


Single Side Highlighted Both Sides Highlighted

Face Split by Points and Edges

• Easy and flexible options for geometry decompositions

• Multiple splits in a single step


stepFace Splits by Points and

Edges

Edge Split by Locations

• Split locations can be specified by mouse click

• Edge direction display is available for split by fraction method


fraction method• Multiple locations on one

or more edges are supported

• Split locations can be modified after the split, by dragging the split points

Edge Split by Locations

Additional Decomposition Tools


Slice a solid by selecting edge loops Splitting a face by screen locations

Face Connect

• Ensures shared topology among faces within user specified tolerance– Support for partial

overlap

Gambit Reader for Workbench

• Legacy model support for GAMBIT databases– Reads Real (ACIS) geometry

from a Gambit database– Does not include reading


– Does not include reading meshing information

– Edit the geometry in DM– Mesh the geometry in ANSYS

Meshing

Faster and Targeted Update

• Model state is compared to identify changes

• Only changed bodies and parts are refreshed

• Meshing update is required


• Meshing update is required only for the changed bodies

• Significant reduction in time for updating the mesh after modifying the model
