This lesson covers the post-processing of displacement values at nodes to produce useful visualizations using Ansys Mechanical™ structural finite element analysis software. It explains how to visualize the deformation of a pressure vessel, verify the model setup, and understand the deformation better. The lesson also discusses how to visualize stress in the model, investigate hoop stress, axial stress, and radial stress in the geometry. It further explains how to create a path running through the thickness of the pressure vessel and plot the hoop stress variation along that line. Lastly, it teaches how to view a full 3D visualization of the results by revolving the axisymmetric model around the Y-axis.
