SS-T: 3060 Structural Analysis with Wind Load

Purpose
SimSolid performs meshless structural analysis that works on full featured parts and assemblies, is tolerant of geometric imperfections, and runs in seconds to minutes. In this tutorial, you will do the following:
  • Learn to apply wind load for Structural static analysis.
Model Description
The following model file is needed for this tutorial:
  • facade.ssp
Figure 1.


The file has the following specifications:
  • Material is set to Aluminum Nitride (AIN) for facades and Steel
  • Regular connections are created between parts

Open Project

  1. Start a new SimSolid session.
  2. On the main window toolbar, click Open Project .
  3. In the Open project file dialog, choose facade.ssp
  4. Click OK.

Create Subcase

On the main window toolbar, click Structural subcase > Structural linear.
The new analysis appears in the Project Tree under Design study 1 and the Analysis Workbench opens.

Create Immovable Support

  1. On the Analysis Workbench, click Immovable support.
  2. In the dialog, verify the Faces radio button is selected.
  3. In the modeling window, select the faces highlighted in orange from the figure below.
    Figure 2.


  4. Click OK.

Create Wind Load Boundary Condition

  1. In the Analysis Workbench, click Pressure and select Wind load.
  2. For Ground position, enter coordinate values with respect to the global coordinate system.
  3. Select the Air density units and enter a value for Air density.
    By default, the air density value is set to 1.2 kg/m3.
  4. Accept the default values for Friction coefficient and Shape factor as 0.01 and 1 respectively.
  5. Select Enable Shielding checkbox.
    Note: The Enable shielding option provides capability to protect components from wind load that are obstructed by other parts. When unchecked, wind load is exerted on all components, regardless of whether the surfaces facing the wind source are obstructed by other parts within the assembly.
    Figure 3.


Define Wind Direction and Height Axis

  1. In the dialog, go to the Wind direction tab.
  2. Enter an appropriate value for Wind profile velocity direction with respect to the global coordinate axis.
  3. Enter 1 along Y-axis.
  4. Go to the Height axis tab.
  5. Enter an appropriate value for Wind profile height direction with respect to the global coordinate axis.
  6. Enter 1 along Z-axis.
  7. Optional: By clicking Flip the axis, the positive or negative direction of the axis can be toggled.
    Figure 4.


Create Wind Profile

  1. In the Wind load dialog, click Edit profile to create the wind profile.
  2. Select Standard from the dialog.
    Standard wind profiles dialog appears.
  3. For Profile type, select Uniform.
  4. For Speed (Velocity), enter 27 m/sec.
  5. Optional: Height above ground (H) is automatically calculated from the model based on the Height direction, which can be edited if required.

  6. Click OK three times to complete wind load creation.
    There are three ways to create the wind profile in SimSolid. Import from external CSV, create from standard template, or create manually.

Edit Solution Settings

  1. In the Analysis branch of the Project Tree, double-click on Solution settings.
  2. In the Solution settings dialog, for Adaptation select Global+Local in the drop-down menu.
  3. Click OK.

Run Analysis

  1. On the Project Tree, open the Analysis Workbench.
  2. Click Solve.
SimSolid runs the analyses in Design study 1. When finished, a Results branch for each analysis appears in the Project Tree.

Review Results

  1. In the Project Tree, select the Structural 1 subcase.
  2. On the Analysis Workbench toolbar, select Results plot ➔ Displacement Magnitude.
