In this video, you’ll:
00:06
identify the correct workflow for the reuse of simulation setup,
00:11
create a simulation based on a model simplification that retains the simulation setup,
00:17
refine a simulation study with modified boundary conditions,
00:22
and create a simulation to accommodate a significant design change.
00:28
Fusion 360 provides many tools to expedite the work of simulation.
00:34
Open the file Refining Simulation Results.f3d in the Simulation workspace and solve the study.
00:43
Once the simulation is complete, notice that it includes a fixed constraint and a 1 kilonewton (kN) load.
00:52
The material used is steel.
00:55
The simulation can be replicated with a change of material, such as using aluminum instead.
01:01
Likewise, the load could be modified, such as placing a 2kN load laterally at the end.
01:10
While this existing setup can be overwritten, it could prove useful to keep it for future reference.
01:17
Instead, duplicate the study.
01:21
To do this, from the Browser, right-click Study 1, and, from the shortcut menu, select Clone Study.
01:29
The Browser updates with a duplicated Study called “Study 2”.
01:35
Expand the nodes for Study Materials, Case Loads, Loads, and Constraints.
01:41
Notice that the cloned study duplicates the materials, loads, and constraints.
01:48
With Study 2 active, you can begin configuring the new setup.
01:54
First, change the study material.
01:58
Under Study 2, select Study Materials, and then click Edit.
02:04
The Study Materials dialog displays.
02:07
In the Study Materials column, expand the (Same as Model) drop-down and select Aluminum.
02:15
Click OK.
02:17
Now, add a new load.
02:20
From the Toolbar, click Loads.
02:23
The Structural Loads dialog displays.
02:26
In the canvas, select a face to which to apply the load.
02:32
Back in the Structural Loads dialog, in the Magnitude field, enter 2000 to apply a 2kN load.
02:42
With the new load applied, you can solve the study.
02:46
From the Toolbar, Solve panel, select Solve.
02:50
From here, you can either choose to solve both studies, or just Study 2.
02:57
For now, select Study 2, and then click Solve.
03:02
For a brief time, the Job Status dialog displays, indicating the progress of the simulation.
03:09
Once it is complete, the canvas updates with the new study results,
03:14
without altering the original study.
03:17
Model complexity can greatly impact calculation time.
03:22
For instances when you must calculate a complex model several times,
03:27
it is useful to simplify the model.
03:30
To do this, from the Toolbar, click Simplify.
03:35
Clone the simulation model.
03:37
From the Browser, right-click Simulation Model 1,
03:42
and, from the shortcut menu, select Clone Simulation Model.
03:47
This opens the Clone Simulation dialog.
03:51
From the list of studies, ensure Study 1 – Static Stress is selected and then click OK.
03:59
The Browser updates with a duplicated simulation model called Simulation Model 2.
04:05
With this model active, in the Simplify Solid > Modify panel, select Remove Features.
04:13
This displays the Remove Features dialog.
04:16
In the canvas, select the main body.
04:19
Depending on which features are checked in the dialog, certain features will be selected automatically.
04:26
In this example, select Chamfer and in the model all the chamfers targeted for removal highlight.
04:34
To manually select features to remove, in the dialog,
04:39
next to Manual features, click the selection tool.
04:43
Then, in the canvas, select the features you wish to remove.
04:48
For instance, select the fillets along the channel.
04:53
To delete both the automatically and manually selected features, in the dialog, select Delete.
05:01
Close the dialog.
05:04
Then, from the Toolbar, select Finish Simplify.
05:07
The model updates with the selected features removed.
05:11
It is important to know that the simplification in the Simulation workspace
05:16
has not affected the actual design of the model.
05:19
Navigate to the Design workspace.
05:23
Here, you can see that the original design remains intact.
05:29
Return to the Simulation workspace.
05:32
The Simplify tool can be used to explore different design options
05:37
without making actual modifications to the model.
05:41
For example, you can explore what would happen to the design if the model were hollow.
05:47
Rather than remodeling it in the Design workspace, open the Simplify toolbar again.
05:54
Under Simplify Solid, expand Modify and select Shell.
06:00
The Shell dialog displays.
06:03
From here, you can make the simulated design hollow.
06:07
To do so, in the canvas, select two faces on either end of the part to remove them.
06:14
Back in the dialog, in the Inside Thickness field, enter 4.
06:19
Click OK.
06:21
The model becomes hollow with an internal thickness of 4 mm.
06:26
From the Toolbar, select Finish Simplify.
06:30
After making a major change such as this, it is imperative to ensure the load case is still valid.
06:38
From the Browser, expand Load Case1.
06:42
Then, expand each Load and Constraint
06:45
and ensure that they are being applied to the appropriate surface.
06:50
Under Loads, select Force1.
06:53
It displays correctly in the canvas and is applied to the appropriate surface.
06:59
Under Constraints, select Fixed1.
07:03
Again, in the canvas, the appropriate constraint appears.
07:08
Finally, regenerate the mesh.
07:11
Right-click Mesh and select Generate Mesh.
07:16
After it processes, the mesh regenerates.
07:21
Solve the study.
07:23
From the Toolbar, Solve panel, select Solve.
07:28
The Solve dialog displays.
07:30
Click Solve.
07:32
The Job Status dialog appears and displays the progress of the solving job.
07:38
When it is complete, the canvas updates with results for the hollowed model.
07:44
From the Toolbar, select Finish Results.
07:47
Ensure the file is saved.
07:50
Again, the original design has not changed.
07:53
You can always inspect the original design by entering the Design workspace.
