Tutorial: Post Processing for Static Analysis (Connecting Rod)

In this article, we will demonstrate how the simulation results of the stress analysis of a connecting rod can be visualized and analyzed in your browser. This tutorial will also show SimScale’s post-processing environment’s capabilities.

Relevant pages:

• Connecting rod stress analysis – public project
• Linear Static Stress Analysis – SimScale Simulation Tutorial

• To begin the analysis, choose the preferred completed run under the ‘Simulation Runs’ option, and then click on the ‘Post-process results’ button to load the results on the viewer.

• The available result datasets are all listed on the left in the tree.
• Clicking on the specific result that you want to visualize to load it into the 3D viewer.
• For example, to check the ‘von Mises stress’ on the model, click on the ‘Results’ and then select the ‘von Mises stress’ from the Scalar (‘SCL’) list below.
• The color scale corresponds to the distribution of the von Mises stress in the model.

• As a next step, the ‘displacement’ field can be displayed on the connecting rod model as a color plot.
• To visualize other physical quantities of the results, for example, the ‘All displacement’ field across the rod, switch again the field on the viewer.

• The colors already give a qualitative understanding of the displacement field. Red indicates large displacement while blue stands for small.
• As the last step, qualitative feedback on the displacement field can be visualized by plotting the displacement vectors.
• Click on the ‘Results‘, then toggle on the ‘displacement’ under the ‘VEC’ option.

• You can now continue analyzing the dataset. For example, you can visualize more color fields such as the strain by applying additional filters (isosurfaces, isovolumes etc).
