Snap cover

This simulation tutorial will guide you through:

  • Applying force loads to the hooks of a snap cover
  • Running a simulation
  • Viewing the stress in the simulation results

Snap cover

Looking for a video? Check out Connecting rod. It's a different model, but the steps shown there are broadly the same as the steps described below.

Import the CAD file

  1. In OnScale Solve, from the Projects tab of the dashboard, create a new project.
  2. In the Tool Bar, click (+) and then Library. Under OnScale Library, Select Snap cover.
  3. Select Millimeters as the length unit.

Assign a material

  1. Using either the tree or the 3D viewer, select Case.
  2. Using the Material dropdown in the properties panel, assign Acrylic Plastic to this part.

Add a fixture

  1. Select the Physics tab.
  2. In the toolbar, select > to fix the surface.
  3. Using the tree, select Face 7, and then click Done.

Add force loads

  1. In the toolbar, select > to add a force load.
  2. Using the tree, select Face 43 (the outside surface of one of the hooks).
  3. In the properties panel, for Force, enter 1 and then select Done.
  4. Repeat steps 1 to 3 for the outside surfaces of the remaining hooks (Face 44, Face 103, and Face 124).

Run a simulation

  1. Select the Simulator tab.
  2. In the properties panel, select MESH & ESTIMATE. This automatically meshes your model, estimates how long the simulation will take to run, and estimates what the likely core-hour cost will be.
  3. Once the meshing and estimation process has finished, use the cost–time slider to select the level of computational resource that you want to use for this simulation.

    By using additional computational resources for the simulation (and hence spending additional core-hours), the simulation can be completed faster.

  4. Select RUN to run the simulation.

Analyze the results

  1. Once the simulation has finished, select Load Results to open the results in the Results tab.
  2. Output categories can be selected from the tree: Select Von Mises.
