DX R13: 02/17/201112

Hybrid Release

Originally intended as a quick point release Some small changes

Bug fixes

Stuff that didnt have time for quality approval at 14.0

But things change, customers ask for stuff Schedule moved up on some key features and capabilities

Development cycle stretched a bit to fit more in More than a point release, less than a major release


13/59

DX R13: 02/17/201113

Big Themes

More meshing

Bringing the new infrastructure forward more

Greater integration between products

Performance

Bolt pretension on 2D


16/59

DX R13: 02/17/201116

Tags You can put names on Objects in your tree Used with filtering

Handy way in large models to group different kinds of objects Select object in tree and then use Add Tag in Tag window

Filtering Ribbon on top of tree

Filter on: Name: Object names, wildcards are implied

Tag: Tags, wildcards are impled

Type: Dropdown of all the object types

State: Dropdown of All, Not Suppressed, Suppressed,

Not Licensed, Undefined. Enter does a refresh and shows

matching objects

Refresh, Clear, Expand buttons

Tags and Filters


17/59

DX R13: 02/17/201117

Object Generator

Copy tree objects thatare applied to geometry

to other geometry You select object in the tree then the geometry you want it

applied to

You can:

Control where it is applied through scoping Apply a name prefix to the objects you create (very nice!)

Apply a tag to everything you create (also very useful)

Good example: You define a beam as a bolt in one hole,

then copy it to a bunch of holes with this Lots of options, play with it to learn it

Topic for future seminar or Focus article.


18/59

DX R13: 02/17/201118

Section Planes

New Edit Section Plane button

Changes under the hood with respect to

meshes that speed things up

M h B d St ff FEA


27/59

DX R13: 02/17/201127

Mesh Based Stuff: FEA

You can make a coordinate system at a node!!!! Click on a node, creates

But it just uses the location of the node, not the node. It does notmove if the node moves on a remesh

You can also make a coordinate system that is aligned witha principal stress or strain value

Result objects can be scoped to nodes- named selection Plot elements by Named Selection

Display Node Numbers Use Annotation preferences

Node picking on result plots

Contact


35/59

DX R13: 02/17/201135

Contact Lots being done here, mostly user driven

User Routines:

USERFRIC: now supports all DOFs and Lagrange New USERINTER to do much more complex interaction beyond

standard contact

USERCNPROP is a new routine to create real constants in a userroutine. Allows you to change contact properties at each substep

Real Constants now support tabular values Works with primary variables (temp, pres, etc..)

MPCs can now be used to couple DOFs

3D Node-Node (178) now supports: Spherical gap

Works with most DOFs: thermal conduction, convection, radiation,heat generation due to friction, external heat flux, electric conduction,and heat dissipation due to electric current.

2 D to 3 D Tools


36/59

DX R13: 02/17/201136

2-D to 3-D Tools New commands to make it easy to convert a 2D solution into a 3D

solution: mesh and solution

Idea is to start in 2D then when needed, convert to 3D to continue Requires that the geometry is extruded in a coordinate systems

EEXTRUDE command does the extruding

Handles contact, BCs, loads, etc..

MAP2DTO3D then maps the 2D results onto the 3D model as the new

starting point Does not work with:

Plane stress and generalized plane strain

Layered or reinforced elements

Enhanced strain

Distributed ANSYS

Remeshing

Diffusion Improved


37/59

DX R13: 02/17/201137

Diffusion Improved

Coupled field elements enhanced to support nonlinearbehavior:

PLANE223, SOLID226, SOLID227 plasticity, viscoelasticity, viscoplasticity and creep in structural-

diffusion and structural-thermal-diffusion

New surface and body diffusion loading: DFLUX, DGEN

Use SF* or BF* family of commands New diffusion elements:

PLANE238: 2D quadrilateral

SOLID239/240: 3D brick/tet

Distributed ANSYS


38/59

DX R13: 02/17/201138

Distributed ANSYS

Lots of under-the-hood work to get it faster and more robust

Key things that users can use:

A new COMBINE command to combine files from multiple machines Use this if you opted to not do the automatic combine, or something went

wrong

Eigensolver used for Block Lanczos and Supernode now use SMPinside a DMP run to extract the modal solution Mixed SMP/DMP

J CG, ICCG, QMR now all use SMP when needed within a DMP run

VT for harmonic now works with distributed

SECFUNCITON now works with DMP (shell thickness as part of atable)

GPU


39/59

DX R13: 02/17/201139

GPU

Lots of work here as well

Improvements in performance

Modifying the code to take advantage ofGPU

Working with supplier to improve things

Multiple GPUs on one box is now

supported Distributed only for Sparce solver

SMP or DMP for PCG/J CG

Larger problems now work with GPUs

If you have not looked at a GPU, it is time.

Acoustics


40/59

DX R13: 02/17/201140

Acoustics

Additions made to the acoustics solver, mostly customerdriven

New fluid model for sound in porousmaterial (TB, PERF) Johnson-Champoux-Allard Equivalent Fluid Model of Perforated

Material - if you dont know what this is you probably dont need it

New BC for surface velocity or acceleration

Far-Field now supports 2D elements FLUID130 infinite element that is a new acoustic boundary

condition

Much more meat has been added to the Acoustic Theory

sections of the Theory Reference

More Additions to Linear Perturbation


41/59

DX R13: 02/17/201141

More Additions to Linear Perturbation

Extended to work with static analysis Used to be just modal/buckling/harmonic stuff

Extended to work with PSD Actually, PSD can now use a linear perturbation modal analysis

Superelements are now supported (MATRIX50)

COMBIN39 nonlinear spring works now

Result Files (* rst)


42/59

DX R13: 02/17/201142

Result Files (*.rst)

Now stores element results in single precision Nodal results are still double

Result files can be 50% smaller than files in prior releases Lots of little changes in the way things are written

Plus principal stresses are no longer stored, they are calculated onthe fly

If you have programs that read RST files, things havechanged Header is longer (80 integers instead of 40)

Multiple sets of geometry are stored in the same file

Principal stresses are gone

Other


43/59

DX R13: 02/17/201143

Other

Submodeling enhanced to make submodeling of non-linearareas more robust.

Isotropic hardening added for Chaboche Curve Fitting Shared Memory Parallel used automatically on a PSD

analysis

Undocumented Stuff


44/59

DX R13: 02/17/201144

Undocumented Stuff The Variation Technology (VT) commands are now undocumented

/VT and VT*

Used for probabilistics Does not impact VT solver tools with cyclic symmetry or harmonic analysis

Reduced Harmonic and Transient methods are gone

The TOTAL command is gone

Used to get Master DOFs for reduced modal

PGR file is no longer supported Bummer compact result file but never really used

SOLID62 old magneto solid element

INTER115 couples magnetic vector and scalar potentials

FLUID79/80/81 are all archived (soon to be undocumented) Contained fluid elements

I question this one. If you use it, speak up!

Meshing &Geometry

Design Modeler


46/59

DX R13: 02/17/201146

Design Modeler Lots of bug fixes and performance tweaks

Focus on improving performance on big models

Lots of work on dealing with DM (NURBS) vs. Workbench (facets) geometry

Impacts performance, files size, repair If you dont need NURBS, dont use NURBS

Facets are much easier to repair

Converting from NURBS to facets can be slow

DM now supports both faceted and NURB geometry(WB or DM)

Imported geometry can be set to Workbench or Design Modeler Conversion from WB to DM is automatic if you operate on it

User can use new Conversion tool to force conversion to NURBS

Importing of points/curves now supports a base plane

You can now do a slice on a shared topology solid

This is kind of a big one

There is now a preview circle that showswhen you are doing an operation thatinvolves a range, gap, or size. Lets you gage your sizes visually
