ANSYS WORKBENCH SYMMETRY

[choupiced]

Consider a beam (Length L) cantilevered its two ends.

It imposes a force F distant to L / 4 and another to 3L / 4. The problem is symmetrical from the center of the beam.

Can I use a symmetry in designmodeler to have an half model
and how can I implement cantilever and force in simulation and perhaps boundary conditions ?

Hi,
yes, symmetry is supported in Workbench.
As to how impose loads and restraints, normal symmetry considerations of statics apply, of course.

The command to be used is "Frictionless support" applied on the surface (= symmetry plane), isn't it?
Thank you very much.

Hi,
well, Frictionless Support is one of the ways you can use for symmetry. Conceptually better is to use the "Symmetric Region" command.
In a near future, Workbench will be able to handle the "general" type of symmetry, i.e. cyclic symmetry, just like Classical does, and I presume the command to be used will be something very similar to the one I mention. In fact, for EMS analyses, the symmetry type "cyclic" already works (note: I'm speaking of v.11).

Hi

Are you modelling a Beam with a Section or is it a solid model?
Because this previous only applies to solids!

Hi

it's a solid model.
Is The function "Symmetric region" in the V.10?

Regards.

Hi,
yes, it is. Click "Symmetry" button in the toolbar, it will insert a Symmetry object in the Outline. Then right-click on this object and choose Insert -> Symmetry Region. Then set the properties corresponding to what you need.
