In this video, you’ll
00:05
• use direct modeling tools to prepare a model for simulation,
00:09
• clone and reuse simulation models,
00:12
• confirm CAD models,
00:14
• prioritize geometry features for analysis,
00:18
• and use inspection tools to validate component interference.
00:23
When preparing for a simulation study, it is important to know that the more complex a model is, the longer the calculation can take.
00:33
In some cases, you may only need to analyze a specific part,
00:38
or you may wish to analyze a model without the features that are unnecessary for simulation, such as fillets or chamfers.
00:47
Using the Simplify workflow in the Simulation workspace allows you to remove unnecessary features
00:54
and simplify the geometry without altering the intended design of the model.
01:00
Open the file Working in the Simplify Workspace.f3d.
01:05
Navigate to the Simulation workspace.
01:08
The New Study dialog appears with Static Stress already selected.
01:14
Click Create Study.
01:17
On the Toolbar, select Simplify.
01:20
The contextual Toolbar changes to show two Simplify tabs: Simplify Solid and Simplify surface.
01:29
For this exercise, you will work with the Simplify Solid tools.
01:35
It is important to understand that any changes made here in the Simulation workspace with the Simplify tools
01:43
will not be reflected in the Design workspace.
01:47
Changes made using the Simplify tools only exist within the Simulation workspace
01:53
and will only be recorded in the Simplify timeline.
01:58
However, note that component position and assembly joints are not captured in Simplify, but components can still move.
02:09
To reduce calculation time, remove all bodies that are not relevant to the study.
02:16
From the Browser, under Model Components, right-click Shaft Collar:1 and, from the shortcut menu, select Remove.
02:27
In the Browser and in the canvas, the model updates with the shaft collar removed.
02:34
Small features are also commonly removed using the Simplify tools to reduce processing time
02:41
and to produce a cleaner mesh for the static stress study.
02:46
Commonly removed features include fillets, chamfers, and embossed text,
02:51
which typically have little to no impact on overall stiffness and do not significantly alter the mass of the component.
03:01
However, these small features can be removed only if they are not part of critical stress regions.
03:09
Using the Remove Features command allows you to filter the features to remove them by size and type.
03:16
From the Toolbar, Modify panel, select Remove Features.
03:22
The Remove Features dialog displays.
03:25
To select features by size, in the canvas, select the body of the model.
03:32
Then, in the dialog, click and drag the Feature Size slider to filter the features by size.
03:40
As you move the slider, smaller to larger features are selected on the body.
03:46
To select features by type, use the checkboxes in the dialog to filter out certain types of features.
03:54
Currently, Select All is enabled, so all feature types within the body are selected.
04:01
Select Fillets to deselect the fillets. Select Fillets again.
04:08
Features may also be manually selected or deselected for removal.
04:12
To do this, in the dialog, next to Manual features, click the selection tool.
04:21
Then, in the canvas, select the features to be removed.
04:28
If you select features you do not wish to remove, simply click them again to deselect them.
04:33
Once the features you wish to remove have all been selected, in the dialog, click Delete.
04:40
The model updates with a simplified display.
04:44
Close the dialog.
04:46
Another option to simplify the model is to use the Split Body command,
04:51
which can be used to remove half of a symmetrical component.
04:55
It is commonly used in static stress studies to decrease processing time or to allow loads to be applied at the center of the model.
05:06
To do this, from the Toolbar, expand Modify and select Split > Split Body.
05:14
The Split Body dialog displays.
05:18
In the canvas, select the body you want to split.
05:22
Then, back in the dialog, next to Splitting Tool(s), click the selection tool.
05:29
Workplanes display that indicate where the split will occur.
05:33
Select one of the workplanes.
05:36
Then, in the dialog, click OK.
05:39
The body is now split in two.
05:43
To remove one of the symmetrical bodies, from the Browser, under Model Components,
05:49
expand Bracket: 1 and then expand Bodies.
05:54
Hover your cursor over Body3.
05:57
One of the symmetrical bodies highlights in the canvas.
06:01
Now, right-click Body3.
06:04
From the shortcut menu, select Remove.
06:08
Removing small features or using the Split Body command can significantly reduce the time it takes to run a study.
06:17
Once you are finished, be sure to save the file.
