Structures
Set up your model and run a structural analysis or optimization.
Model Setup
Create connections and apply loads, constraints, materials, and manufacturing controls to your model.
Loads and Constraints
Apply loads and supports, displacements, accelerations, gravity, temperatures, and center of gravity.
Accelerations
Use the Accels tools on the Structure ribbon to apply g-Loads and angular velocity/acceleration.
g-Loads
g-Loads are used to simulate a model undergoing acceleration, which imparts a force on all of the parts in the model.

- Model Setup
  Create connections and apply loads, constraints, materials, and manufacturing controls to your model.
  - Connections
    Create and define connections such as fasteners, joints, connectors, spot welds, and contacts.
  - Loads and Constraints
    Apply loads and supports, displacements, accelerations, gravity, temperatures, and center of gravity.
    - Loads and Supports
      Use the Loads tools on the Structure ribbon to apply forces, pressures, torques, and supports to your model.
    - Displacements
      Use the Disps tools on the Structure ribbon to apply enforced displacements and displacement constraints.
    - Accelerations
      Use the Accels tools on the Structure ribbon to apply g-Loads and angular velocity/acceleration.
      - g-Loads
        g-Loads are used to simulate a model undergoing acceleration, which imparts a force on all of the parts in the model.
      - Angular Velocity/Acceleration
        Angular velocity (ω) defines the speed of rotation of the entire model and the axis about which it rotates. Angular acceleration (α) is the rate of change of the model's angular velocity.
  - Materials and Libraries
    Create materials, assign materials to parts, and organize them into libraries.
  - Concentrated Masses
    Use the Masses tool to create a concentrated mass either on a part or at a point in space.
  - Systems
    Use the Systems tool to create and apply user-defined coordinate systems to loads, supports, and displacements.
  - Manufacturing Controls
    Apply manufacturing constraints using shape controls and bead patterns.
  - Mesh Controls
    Use mesh controls to assign an element size to parts or faces.
  - Temperatures
    Use the Temperature tool to simulate the effects of temperature changes on your model.
  - Center of Gravity (COG)
    Use the Center of Gravity Constraint (COG) tool to apply, reposition, and set upper and lower bounds for a center of gravity constraint. COG constraints are used to limit the position of the center of gravity while running a topology optimization.
  - Gravity
    Use the Gravity tool to apply gravitational acceleration (G) and adjust its direction.
- Structural Analysis
  Set up and run a linear static analysis using the SimSolid or OptiStruct solver. You can also analyze normal modes and buckling modes.
- Structural Optimization
  Set up and run a topology, topography, or gauge optimization.
- Report
  Generate PPT or PDF reports from analysis results. The Report tools are available after you have run an analysis.
Motion
Set up and run a motion analysis, plot the results, and export the results.
Fluids
Prepare and run a computational fluid dynamics simulation.
Design Explorer
Evaluate designs by using geometric variables and applying a design-of-experiments (DOE) or optimization method. We recommend fully constraining your sketch when sketch variables are used in the design exploration.
Manufacture
Set up and run a basic porosity or thinning analysis.
Print 3D
Prepare and run an additive manufacturing simulation, and export a file for 3D printing.

g-Loads

g-Loads are used to simulate a model undergoing acceleration, which imparts a force on all of the parts in the model.

Apply g-Loads

On the Structure ribbon, select the g-Loads tool.

Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
Click the point on the model where you want to apply the g-Load.
Enter the magnitude of the g-Load in the text field of the microdialog and press Enter.
To reverse the direction of the g-Load, click the +/- button on the microdialog.
Right-click and mouse through the check mark to exit, or double-right-click.

Tip:

g-Loads are applied to the entire model rather than a part, and are specific to a load case. If you delete the part where the g-Load is applied, it remains in the model.
Use the right-click context menu to include or exclude a g-Load from a load case.

Orient g-Loads Using Vectors or Components

You can orient a g-Load by using either vector g-Loads (X, Y, and Z) or component g-Loads (gX, gY, gZ).

Select either vector g-Load mode or component g-Load mode on the microdialog.
Click the chevron to expand the microdialog.
Enter either vector g-Loads (X, Y, and Z) or component g-Loads (gX, gY, gZ).

Microdialog Options

Double-click on a g-Load arrow to enter editing mode, which opens a microdialog.


	Change the direction of the g-Load.
	Enter a magnitude of the g-Load.
	Click the icon to switch between vector g-Load mode and component g-Load mode.
	Translate or rotate the g-Load using the Move tool.
	Align the g-Load to the X, Y, or Z axis.
	Click the chevron to orient the g-Load by entering either vector g-Loads (X, Y, and Z) or component g-Loads (gX, gY, gZ).
