Generative Design enhancements for Solid Edge 2019

Siemens Experimenter Siemens Experimenter

 A lot has happened in Solid Edge Generative Design since its launch in ST10. Generative Design was always fun to use to experiment with different shapes for your part design. Now it is even easier to  compare and use the resulting bodies. 

 

Here is a look at the changes, in no particular order. 

Creating or editing a generative study

Note

 See the Generative Design workflow help topic for examples of how to create a generative design study.

 

  • When you define a load, constraint, or region, Generative Design now recommends a material offset value that is based on the default study quality instead of a fixed value. For more information, see the Generative Study dialog box help topic.
  • In the Generative Design pane, you can double-click a study input object—such as material, design space, load, constraint, or region—to edit it directly. 
  • You can use Ctrl+drag to duplicate a load, constraint, or region in the appropriate container within the same study.
  • New shortcut commands—ExpandCollapse,Expand AllShow Only—are available in the Generative Design pane to aid in working with generative study input objects. 

 

Edit handles show values

When you click a defined region, load, or constraint object in the Generative Design pane, the edit handle that is displayed in the graphics window now shows the object name, as well as its defined value. Previously, you had to edit the object to see the values assigned to it.

Example

Generative study data tips

Data tips are now available for individual studies, regions, loads, and constraints when you hover over an object in the Generative Design pane. Data tips let you quickly review the settings you used to optimize a part, as well as the values you assigned to individual generative design study objects.

Use synchronous technology to modify your part in Generative Design

Based on the results of the structural optimization, you may decide you need to improve the original part design before you optimize it again. For example, you may need to simplify the original part, or thicken it, or change the diameter of a hole, or add a cutout. You can switch fluidly between making synchronous edits to regenerating and updating your mesh body result.

  • To edit the model, first select the Design Body 1 entry in PathFinder to display the original part body, and then modify it using any synchronous modeling commands on the ribbon.
  • To reprocess the generative study using the same loads and constraints, display the Solid Mesh Body 1, under Construction Bodies, and then select the Generate command again.

More manufacturing settings manufacturing_settings_icon.png

New options are available for specifying requirements that support traditional manufacturing methods, such as casting and milling. Look for these in the Manufacturing Settings dialog box (Generative Design tab→Generate group→Manufacturing Settings command.)

  • To generate a part with a constant cross-section thickness, use the Material Extrusion Axis list to specify the axis and whether it is unidirectional or bidirectional.
  • To choose how material is distributed along the part as it is optimized, use the Material Spreading slider.
    • 0%=no effect
    • 30%=hollowed-out solid areas
    • 60%=thin-wall structures
    • 100%=strut-like structures

For examples, see the Manufacturing settings help topic.

Structurally optimize mass within a factor of safety  generate_command_gd.png

A new option is available for optimizing the mass of your part. Rather than specifying a target mass value to achieve, you can choose to reduce the mass within the limits of a factor of safety. The Use factor of safety option is available in the Generate Study dialog box when you select the Generate command.

 

For more information, see the Generate Study dialog box help topic.

Pinned constraint changes  pinned_constraint_command_gd.png

When you use the Pinned command, which constrains movement in the X, Y, and Z planes while allowing rotation:

  • Geometry selection is limited to cylindrical and conical faces and features.
  • The axis of rotation is set to match the axis of the selected geometry.

New command: Create Load Case  load_case_command.png

For a part that is likely to undergo opposing forces during operation, you can use the new Create Load Case command to account for these conditions during structural optimization.

Example

A part can have opposing forces which may or may not be equal, such as:

  • Internal pressure and external pressure, like that in a pressure vessel or on a push-pull knob.
  • A lever that moves in two opposing directions.

 

Example

A part can have opposing torques, which may or may not be equal. An example of this is a door knob that can be rotated clockwise or counterclockwise.

 

The Create Load Case command groups loads and constraints in the order in which they will be applied during operation. For more information, see Using load cases.

 

New load command: Gravity   gravity_load_gd.png

You can apply a general gravity load to the body in the design space during structural optimization. For more information, see the Gravity load command in help.

 

Because gravity is applied to the entire design space, it is listed in the Generative Design pane in the general study definition area as either Gravity (Undefined) or Gravity (Defined). It is not listed under the Loads collector.

 

New constraint command: Displacement   displacement_constraint_gd.png

A new Displacement Constraint command is available to define a face or feature that is allowed to move in a specified direction and for a limited distance before it starts to deform. For more information, see the Displacement constraint command in help.
