Connecting rod

This simulation tutorial will guide you through:

  • Applying a pressure load to a connecting rod
  • Running a simulation
  • Viewing the displacement in the simulation results

To get started, you’ll need to download connecting-rod.step to your computer.

Connecting rod


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 Millimeters as the length unit.

Assign a material

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

Add a fixture

  1. Using either the tree or the 3D viewer, select Face 65.
  2. Select the Physics tab.
  3. In the toolbar, select > to fix the surface.

Add a pressure load

  1. Using either the tree or the 3D viewer, select Face 63.

    The title of the tree is a dropdown. Select it and then select Model Tree to view the list of faces. This lets you select a face while remaining on the Physics tab.

  2. In the toolbar, select > to add a pressure load.
  3. In the properties panel, for Amplitude, enter 2000000 (2 MPa) and then select Done.

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 View results to open the results in the Results tab.
  2. In the controls, expand Dataset and then select Y Displacement.
