- [Narrator] In this example I'm going to be showing you
a work around to analyze multiple parts all inside of
Simulation Express.
Now you might already know that Simulation Express can
only analyze one part at a time, or even one part of
a multi-body part.
It can only handle, basically, one item.
If you want the ability to analyze a full assembly
or something like that you have to go to the full version
of Simulation.
But in this case here we only have Simulation Express
and I'm going to show you the work around to bring in
multiple parts and bring the into one body.
Alright, so you can see here I've created this bracket
and then I've got a couple bolts here that have beeen
brought in and then combined together.
And that's the process.
So let me show you how it works.
Up here, Insert, Part.
Come over here, I already have this part here, 3.2-1.
Click on Open and I'm going to place one over here
and go ahead and mate it together.
So I'm going to choose this outside surface here
and that one right there, they slide together.
Let's flip them around, add that,
that surface there, spin this thing around,
and that surface there, they slide together.
Looks great.
Okay, we've added one more bolt and let's try that
one more time.
So again, Insert, Part, choose the same part,
click on Open.
I'm going to choose this little area right over here.
And notice right over here I have the option to bring
these other things in, like planes and axis and so on.
But I don't really need anything else besides the body.
And then down here it says "Locate part with move copy
"feature automatically" and that's what we do want to do.
Click there.
And now I'm going to choose the outside surface,
that hole, spin it around like I did before,
click on Add that surface.
This surface right there, add those together,
and click on Add and click OK.
And now we've added four bolts to our part.
Right, now here's our combine feature I already used
and combined those three parts so let's just go ahead
and move that down to the bottom.
Which we can reorder our features pretty easy that way.
And then right click on and say Edit Feature,
and of course let's make these other parts part of the
show here.
So I'm going to combine you and you together
and click OK.
But it says, "Hey why is this guy down here?
"That doesn't make any sense?"
And that's the problem, I'm sure.
So let's get out of that and see why he's down there.
So if that doesn't work let's just delete it out
because maybe that's just causing a problem and
just do it one more time.
Actually, sometimes this indirect editing.
So I'll go over here to Combine, bodies to combine
I want this one, that one, that one, and that one.
Click OK and all of a sudden we have one body.
Hang on it says two bodies.
That one and that one.
Why does it not like this guy?
Let's try it one more time.
That body and that one, click OK.
Alright, we had to do it twice but that's okay
because we got a little bit of extra practice.
Now we have two features here and we could clean that
up if we wanted to.
But we're really just trying to use the feature and
figure out how it works.
So I'm going to run with it.
Next thing I want to do is run an analysis.
Right, we've got just one body so we should be good to go
to go up here to evaluate.
I'll just go over here to Simulation Express.
Let's go ahead and click on Next.
As far as a fixture, let's go ahead and edit an existing
fixture, the fixture is right here.
And go ahead and edit it.
And I'm holding the outside of those two bolts fixed.
Let's go ahead and add these other ones into that,
click OK, looks great.
Down here as far as the force.
We're going to be applying a 200 pound force to this
surface right here.
Click on loads, we can edit that if we needed to.
And then Material, Plain Carbon Steel,
click on Next, run the simulation.
Here we go.
So we're pushing on that lower surface there,
it's deforming.
That looks good.
Show the von Mises stresses, you can see here I'm
bolting this down pretty well.
The bracket's flexing, as expected.
Everything looks pretty descent, we've got a factor
of safety of over one.
So it's not going to fail, at least.
And there it is.
I've brought in five individual parts,
not into an assembly, but into an individual part itself
and I was able to run a simulation on it and it's got
pretty decent results, very similar to what you might have
if you ran this as an assembly.
However, we don't have that ability in Simulation Express.
So there it is simulated as a part.
