Tuning Fork

This simulation tutorial will guide you through:

  • Changing analysis type to modal
  • Running a simulation
  • Viewing the modes in the post processor

To get started, download the CAD file.


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 Modeler, import the CAD file. Select Meters as the length unit.

Assign a material

  1. Using either the tree or the 3D viewer, select Body Frame.
  2. Using the Material dropdown in the properties panel, assign Structural Steel to this part.

Add a fixture

  1. Select the Physics tab.
  2. In the toolbar, select > [svg-fixture] to fix the surface.
  3. Using either the tree or the 3D viewer, select Face 0.

Change Analysis Type

  1. In the Physics tree select Mechanical Environment. On the right the Mechanical Environment settings will be displayed
  2. Click the edit icon.
  3. In the properties panel, change Mechanical Analysis Type to Modal

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: Under Modes select Mode 4.
  3. Click the play icon.
