ParaView Visualization Exercise ​

This exercise asks you to visualize your cantilever beam study in ParaView: open the mesh/results, show the mesh, display a scalar field (e.g., displacement magnitude or stress), apply a few filters, and share clear screenshots of each step.

Time: 15–25 minutes Deliverables: 4–6 screenshots (listed below)

Step 1 — Open the mesh and results in ParaView ​

  • Launch ParaView. If you haven’t installed it yet, follow the install page first.
  • Go to File → Open and select your mesh or results file from the cantilever beam exercise (e.g., cantilever_beam.med, mesh.vtk, results.vtu/results.xdmf).
  • In the Properties panel, click Apply to load the dataset into the Pipeline Browser and Render View.

Screenshot A: The dataset loaded and visible in the Render View with the Pipeline Browser and Properties panel shown.

Step 2 — Show the mesh clearly ​

  • In Display settings, switch Representation to Surface with Edges (or toggle Wireframe) to make elements visible.
  • Adjust the camera to get a clean, orthographic view of the beam; reset camera if needed.

Screenshot B: Clean mesh view of the cantilever beam (Surface with Edges), Pipeline Browser visible.

Step 3 — Visualize a scalar field ​

  • Use the Color By drop-down (toolbar) to color the beam by a scalar field from your solution (e.g., displacement_magnitude, von_mises_stress, temperature, or your field name).
  • Click Rescale to Data Range for a meaningful color map.
  • Optionally switch to Surface for a smooth look and keep the scalar bar visible.

Screenshot C: Scalar field visualization with the scalar bar visible (and mesh edges on/off as you prefer).

Step 4 — Apply core filters and compare ​

Apply at least two of the following filters to your loaded result. Remember to select the dataset node in the Pipeline Browser before adding each filter.

  1. Slice — Create a mid-span or mid-thickness slice to inspect internal variation; position the plane appropriately, then Apply.
  2. Clip — Clip from the fixed end to expose interior fields; tune plane normal/offset, Apply.
  3. Threshold — Highlight high-stress (or high-displacement) regions by setting a value range.
  4. Warp by Scalar — Exaggerate deformation using displacement magnitude for presentation (set a sensible Scale Factor).

Tips: Use the eye icon to toggle visibility between filtered/original nodes and keep your color map consistent for comparisons.

Screenshot D: One filtered view (e.g., Slice) with the scalar field visible. Screenshot E: A second filtered view (e.g., Threshold or Warp by Scalar) showing highlighted or exaggerated regions.

Step 5 — (Optional) Quick plot or export ​

  • Plot Over Line through the beam length to show field variation along its axis, or open Spreadsheet View to inspect values, then Save Data to CSV if needed.
  • Save Screenshot for your report (set resolution/background, include scalar bar).

Screenshot F (optional): Plot Over Line chart or a high-resolution saved screenshot view.

Acceptance checklist (pass/fail) ​

  • ParaView file opened correctly and Apply used.
  • Mesh clearly visible with appropriate representation (edges or wireframe).
  • At least one scalar field visualized with proper color scaling.
  • At least two filters applied (e.g., Slice + Threshold/Clip/Warp by Scalar).
  • (Optional) A plot or exported screenshot/data created correctly.

If anything looks different on your setup, that’s okay — ensure the Pipeline Browser, Properties/Display panels, and Render View remain visible so reviewers can verify each step of your workflow.
