Create an editable generative design.

00:06

After completing this video,

00:07

you'll be able to create a design from a selected outcome

00:10

and create a match from a selected outcome

00:15

in fusion 360.

00:16

We're going to carry on with our internal combustion engine

00:19

gen design set up inside of the explore workspace.

00:23

In the previous video,

00:24

we were able to create a design from the outcome and a mesh design from the outcome.

00:31

Once these have been completed, when we view the outcome,

00:33

we're able to select the mesh design to continue and open it up in fusion 3 60.

00:39

Next, we can go back to our outcome view and we can do the same thing with the design,

00:44

select open design and allow it to open and generate that design in fusion 360.

00:49

A couple of things that we want to note with each of these options.

00:52

The new designs are in a new untitled

00:54

document which means they are no longer connected

00:57

or related back to the original geometry we set up in our generative design study.

01:02

Another thing of note is that the generative design outcome has a free form body,

01:07

a boundary fill feature as well as a combined feature

01:11

to remove all of the obstacles from the design.

01:14

When we take a look at the mesh design, this is opened up without history turned on.

01:18

This means we have direct access to all the mesh editing tools.

01:22

However,

01:23

we cannot do any direct edits to any of the original obstacles or preserve regions.

01:29

So when we take a look at the design by rolling back our timeline before the combine,

01:34

this is going to bring back all the obstacles in our design.

01:37

Notice that all of these bodies are named obstacle

01:40

and they can be hidden in the browser.

01:42

This is going to leave a smoother transition between

01:45

our free form body and the preserved regions.

01:48

If we want to make any adjustments or changes, we can use things such as split body

01:54

and our selections to remove additional areas inside of our design.

01:59

This can make quick work of cleaning up a generative design.

02:03

In this case, the inside features look relatively clean

02:07

and this is a design that we could take directly to manufacture.

02:11

But before you ever take a generative design to manufacture,

02:15

you should always add your additional features

02:17

such as champers or additional hole features

02:20

as well as validate it through simulation.

02:23

Whenever we export a design from fusion 3 60 generative,

02:27

we can navigate to the simulation workspace

02:30

and we can automatically bring in the data from our generative design.

02:34

We're gonna select yes to input that data into our static stress analysis.

02:39

In this case, I'm not going to toggle on the simulation extension

02:43

as our static stress simulation can be solved for free.

02:47

I do want to enter the simplify workspace, expand the model components and bodies

02:52

select all of my obstacles as well as that small piece we removed

02:56

right click and select remove. This is going to leave only the connecting rod

03:01

we're gonna finish simplify.

03:03

And from here note that there is a

03:05

warning because one or more references are missing.

03:08

If we simply activate each of these load cases and take a look.

03:12

Let's go ahead and edit this

03:14

and note that everything here appears to be fine

03:17

in some instances, we will be able to regenerate the solve.

03:21

But in some cases,

03:22

you might find that you need to activate each of these load cases and

03:26

simply do an edit to make sure that the face is still selected.

03:31

So let's carry on and make sure that we adjust each

03:34

of these load cases to make sure that they're all correct.

03:38

We'll just simply activate each one as we go along.

03:42

Edit and just hit enter on the keyboard.

04:15

Once we've ensured that all of the load cases are correct.

04:18

From here, we can simply solve the simulation study

04:21

once again, static stress simulation can be solved for free on the cloud.

04:25

So we're going to select solve one study,

04:28

go ahead and navigate to an appropriate location.

04:31

In your project and name the design, then select save

04:37

while we're waiting for the simulation to solve.

04:39

Let's take a look at the mesh design.

04:42

The mesh design has all of the smooth details that we would expect to see.

04:46

But once again,

04:47

because we don't have direct access to the obstacles and preserves fixing

04:51

geometry like this flat section would take quite a bit more work.

04:55

Another thing to consider with the mesh design is that we don't

04:58

have direct control over specific features on the inside of these bores.

05:03

In order to fix that, we would need to create a new cylinder in the solid tools.

05:08

And then we would need to convert it to a mesh

05:10

and then use it as a bole

05:12

to subtract.

05:14

This can be a little bit tricky and this is something that is not necessarily needed.

05:18

In all cases.

05:20

In this case, what we're gonna do is add a vertical constraint between the cylinder

05:26

and we're going to make sure that we have

05:28

an appropriately sized circle using my dimension tool.

05:31

We can add a dimension of 12.5 millimeters.

05:37

This can be extruded using the extrude tool.

05:40

And we're going to set the direction to symmetric

05:43

with our mesh tools. We can then use the

05:46

tesselate option to convert this to a mesh body.

05:49

We can preview the mesh resolution

05:51

and then we can use the combined option

05:54

to use the removal option to cut this away

05:58

the target body is going to be the main body

06:00

and this new cylinder is going to be our tool body.

06:04

We say, OK,

06:05

and this will allow us to use the mesh tools to

06:07

remove that material from the inside of our connecting rod.

06:13

When we take a look at the results,

06:15

we can now see that we have a more true cylinder on the inside.

06:19

But once again,

06:20

this can often be a little bit more work

06:21

than simply working directly with the free form body.

06:25

We can see that our factor of safety is coming up at 6.89,

06:29

which is slightly higher than the factor of safety that was listed

06:33

inside of our generative design study.

06:35

We can take a look at the various load cases

06:38

to see which one has the lowest factor of safety.

06:41

And we can also take a look at things like the stress distribution.

06:44

As we take a look at the five degrees,

06:46

you can see the stress is higher on this file here.

06:50

And if we take a look at the positive five degrees, as we would expect,

06:54

it's on the other side of the design.

06:56

So as we're thinking about these generative designs,

06:58

it's gonna be exploring each of these different load cases, 10 degrees, 15 degrees,

07:10

it's going to take a look at each of these.

07:12

As it's considering the final solve,

07:14

we can see the area of low stress reference is right on that ridge in the center

07:18

and the areas of higher stress reference are going to be in

07:21

these sections right close to the area where we applied the load

07:27

at this point. We've taken a look at exporting these designs as a solid and a mesh.

07:32

We looked at the benefits of using the

07:34

design export and carrying over the simulation data

07:37

and some of the techniques that we can use to post process these generative designs

07:42

at this point,

07:43

make sure that you do save all of these before

07:45

moving on to the practices and challenges in the course.
