- [Narrator] Having set up the half symmetry model
it's now time to run the analysis and
compare the results to the full model
which was created and run in a previous course.
So let's run the analysis,
run this study.
Now we have the results
so let's right mouse click on stress one von mysis,
And choose chart options.
Set the maximum annotation flag.
We can see where that value is, 34,360 PSI.
In the definition let's change the deform
shape from automation to a more sensible
user defined scale.
Let's choose 60.
And under the settings tab
let's change the fringe options
from continuous to discrete.
And we'll leave the boundary options as model at the moment.
So check okay.
Let's go to a standard solid works view of the front.
Zoom in to the little end region.
Go to plot tools
and select animate.
The default five frames will be buffered,
and then it's running.
Let's stop that animation,
reset the number of frames to a more useful number,
say 16, and then replay that.
Again it buffers the frames.
Notice how the deformation is sliding
along that symmetry plane.
There's no crossing of the symmetry plane
and that's exactly what that constraint is intended to do.
Just spin it around again.
We can see the plane is defining that sliding motion.
Let's stop the animation.
Come back to a side view.
Exit from the animation
and let's look at that maximum stress value,
again 34,360 and that's very similar
to the result using the full model.
Let's right mouse click on stress one von mysis again.
Select chart options,
select definition,
choose the advanced options
and there's a box here display symmetric results
so let's check on that
and click okay.
Now we see a virtual image of the symmetric result
shown underneath the symmetry plane.
Again, just to emphasize it is a virtual image
this is the real result with the real mesh,
this is it's virtual counterpart.
This is very handy to visualize
what would be happening across the full model.
However, it's very important to emphasize
that when you're reporting these results
you must make it clear that this is a half
symmetric model being run,
and that the display is a virtual display
on the missing side.
So at that point let's save our solid works model.
And we'll save it as advanced four.
So in conclusion, in this video
we've seen how to run half symmetry model,
the deformations on the symmetry plane
remain in plane,
and the peak stress is similar
to the full model analysis,
but with a big saving in run time.
Again the full visualization
which includes that virtual half is very useful.
