Integrated post-processing: Solid mechanicsΒΆ

Find below an example on how the simulation results of a stress analysis of a connecting rod is analyzed.

  • First, we switch to the Post-processor tab which will show up initially empty.

  • The available result datasets are all listed on the left in the tree
  • Clicking on the specific result that we want to visualize loads it into the 3D viewer

  • As a next step, we first want to visualize the displacement field as a color plot
  • So we switch in the ‘Result field control’ to the ‘Displacement’ field (it initially says ‘Select field’)
  • Once we did that, the 3D view will be immediately updated to show the displacement field color coded

  • The colors already give a qualitative understanding of the displacement field. Red indicates large displacement while blue stands for small.
  • To see the quantitative values of each color, we click on the ‘color scale’ icon next to the dataset within the pipeline browser (here called ‘Tension-case 1’)
  • In the left of the 3D viewer window, the color scale shows up that provides us with the values for the different colors

  • As a last step, we will generate a visualization that gives a qualitative feedback on the displacement field
  • We click on the green “Add filter” button which shows the available filters that can be used to analyze the dataset
  • We choose the “Warp by vector” filter that allows to visualize a deformation of a shape
  • Once applied, the settings of the filter appear - especially the “ScaleFactor” is of interest. It allows to a exaggerate the deformation to also see very small deformations.
  • We choose “10000” which basically means that a deformation of 1mm will appear as 10m which allows to see even the very small deformations present in this simulation result

  • You can now continue analyzing the dataset for example by visualizing more color fields such as the von Mises stress or strain or by applying additional filters
