Flexible Dynamics DEMO, Steve Pilz, ANSYS Inc.
Recommended (usual) Procedure:
Start projects with rigid bodies and
joint connections (fastest solves), work out the proper dynamic solution
settings. Then, move to a model with perhaps some flexible bodies
and convert some joint conditions to contact regions (slower). If
needed, finally move to all flexible bodies and joints or contact pairs,
as needed (slowest).

WorkBench 11.0 - Tips & Tricks, Shawn Catlin, MTI
Tips
& Tricks Presentation (1.8 MB PDF file)
NOTES:
- Material Data Library (XML
file) - ONE library file can contain many different material
definitions
- Files created during solution may be
retained. This is controlled by Analysis Settings > Analysis
Data Management (In the Simulation - Tree Outline and Details
area). Check the settings for:
- Future Analysis: None
- Save ANSYS db: No
- Delete Unneeded Files: Yes
- IF any of these settings are
changed, additional files are retained after a solution (may
effect disk space significantly)
- DesignSimulation allows definition of
a Hydrostatic Pressure - pressure varies with fluid depth.
Direction and free surface position can be defined. Would no
work for wind loads on a surface (still need surface effect elements
to accomplish wind loading)
- DesignSimulation allows definition of
an Elastic Support (provides an elastic foundation stiffness
btw. the model and "ground"). Can act as an
"isolator"
- All licensing includes the "What-IF"
studies in DesignXplorer - change parameters (via Parameter
Manager) and re-evaluate a model's response. Need add-on
module if you want to use Design of Experiments, Goal Driven Opt,
Robust Design, or Six-Sigma opt.
- DesignModeler has
"primitives" (sphere, cyl, cone, box, etc.)
- DesignModeler now has a Symmetry
feature which cuts a model, keeps the portion on the
positive side of the symmetry plane, and, when passed to
DesignSimulation, creates a Symmetry folder in the tree outline and
applies proper constraint for symmetry.
- DesignModeler: Understanding multi-body
parts is important - "Form New Part" allows several
bodies to act as a single part and effectively "glues
volumes" together without later using bonded contacts.
Also, important to understand "Freeze" and
"Unfreeze" behavior - if operating on unfrozen bodies and
they touch, they will automatically merge. Freezing one or
more bodies keeps it from merging with adjacent bodies.
- DesignModeler, IMPORTing CAD
geometry:
- can choose to import bodies as
"frozen"
- cannot import a CAD assembly that
has BOTH solid and surface bodies - must do two imports (one for
solid bodes and one for surface bodies) using the same CAD
geometry file
- various geometry
"healing" options are available (natural, patch, no
healing)
- DesignModeler new feature for "Slicing"
a frozen body - can use a surface on a body to slice with (instead
of making a new sketch/extrude it for each slice)
- DesignSimulation Contact
Detection/Management:
- BEFORE solving, INSERT a Contact
Tool under Connections in the Model part of the Tree Outline
- Use Right Mouse to Generate
Initial Contact Results
- view the initial status, initial
gap, or initial penetration displays
- "Initial Information"
table shows contact type, status, no. of contacting,
penetration/gap, pinball size.

Topics for Next Meeting / Closing
planning next - March 2008, student presentations
Expecting ANSYS 12.0 release in mid-2008: late summer or fall meeting can
plan for new features presentations. |
