    ANSYS 14.5 Mechanical Cool Stuff • One hour is not enough time to cover everything • Going to skip over 2/3 of what is new, focus on what is the

    most useful – Productivity – New capability

    • More in-depth information – ANSYS, Inc. Webinars – The Release Notes – Upcoming The Focus and Webinars

  • DX R13: 02/17/2011 11

    What 14.5 is About

  • DX R13: 02/17/2011 12

    Hybrid Release • Originally intended as a quick “point release”

    – Some small changes – Bug fixes – Stuff that didn’t 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

  • DX R13: 02/17/2011 13

    Big Themes • More meshing • Bringing the new infrastructure forward more • Greater integration between products • Performance

  • DX R13: 02/17/2011 14

    ANSYS Mechanical

  • DX R13: 02/17/2011 15

    More Flesh on the Bones – General Stuff • Coupling to remote points

    – Long needed, used APDL in the past. Now built in

    • Distance option on Named Selection Worksheet – Specify a coordinate system and a distance: sphere, cylinder, cube – Avoids multiple lines to specify

    • Random Colors – Assigns random colors to a large complex model to make it easier to

    see

    • Bolt pretension on 2D

  • DX R13: 02/17/2011 16

    • 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

  • DX R13: 02/17/2011 17

    Object Generator • Copy tree objects that

    are 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.

  • DX R13: 02/17/2011 18

    Section Planes • New Edit Section Plane button • Changes under the hood with respect to

    meshes that speed things up • Turning on Show Mesh now works with section planes • Bottom line: Allows you to drag section planes on the screen

  • DX R13: 02/17/2011 19

    Stuff that got Sped Up • Fixed some animation things to make it up to twice as fast • Graphics for very complicated assemblies sped up • Issues with copying very large tables have been resolved,

    10x faster • Cyclic symmetry worked on a lot

    – 25%-50% faster in many – A ton of memory changes and improvements to get some major

    reductions in memory that results in better times as well

  • DX R13: 02/17/2011 20

    Pre-Stress Model Superposition • You can link a modal superposition

    transient structural run to a pre- stressed modal analysis

    • In the past it was just a modal analysis

    • Now it can be pre-stressed • Shows up in details for Transient

    Initial conditions

  • DX R13: 02/17/2011 21

    Submodeling • Big Improvement in Mechanical that required

    scripting/MAPDL before • Refined model • Superimpose course model deflection/stress field onto

    detailed model • Huge time saver • Much more accurate

    solutions • At 14.5 supports

    solid elements • Thermal & Stress

  • DX R13: 02/17/2011 22

    Submodeling • Make your coarse model • Make your submodel, dragging the solution from coarse onto

    submodel setup – Don’t drag the submodel onto the coarse model

    • Supports 2D to 3D • One of the more important enhancements at 14.5

  • DX R13: 02/17/2011 23

    Fracture Mechanics • Added to Mechanical at 14.5, first steps

    – Long time in MAPDL

    • Does actual crack modeling – Generates local mesh or you can use your own mesh

    • Uses coordinate systems to specify crack position and orientation

    • A lot of features and capabilities

  • DX R13: 02/17/2011 24

    Composites • You can now do solid composites in Mechanical

    – Used to be shell only – Works with ACP

    • Very useful for – Thick geometry – Combining composites with non-composites in a single model

  • DX R13: 02/17/2011 25

    Contact: Connection Matrix • Tool for viewing how parts are connected • Lots of tools to configure it • A legend describes what the connections are • To get:

    – Click on connection branch in tree – Click on Worksheet Icon – Show preferences and click “Connection Matrix” – Generate or Refresh

  • DX R13: 02/17/2011 26

    Connections: Other • Penetration tolerance is now an option for

    Augmented Lagrange and program controlled contact

    • Force Frictional sliding and Elastic Slip are now supported

    • No separation is now supported for rigid body modeling

    • New joint: Radial gap stop! – Think of a cylinder in a cylinder with a gap and the

    inner cylinder and translate and tilt • Trim Contact option reduces contact pairs • Nonlinear stiffness for rigid body analysis

    for springs and bushings • Bearings now supported for RotorDynamics •
