ANSYS Workbench Post-Processing and Result Analysis: Beginners Guide Episode 6 (Updated June 2026)

Here's the thing — running a simulation in ANSYS Workbench is only half the job. The other half, the part that actually communicates your engineering judgement to a client or a design team, is post-processing. What most people don't realize is that manufacturing companies like Bajaj Auto (Akurdi, 164+ openings), Mahindra and Tata Technologies don't just want engineers who can click Solve — they want engineers who can read results, spot unrealistic outputs and write a report that a project manager can act on. Episode 6 covers exactly that: interpreting your simulation results with confidence.

Understanding Deformation Plots in ANSYS Workbench

After your ANSYS Workbench simulation solves, the first result you will typically insert is Total Deformation — a colour-coded map showing how much every point on the part has moved under the applied load. The colour scale runs from blue (minimum deformation) to red (maximum). Before interpreting anything, check the unit system in the project settings. A deformation of 2.3 displayed in millimetres is manageable; the same number in metres means your design is catastrophically wrong. Directional Deformation lets you isolate movement along a specific axis — useful when a shaft can deflect in one direction but not another. Always compare your maximum deformation against your design tolerance. If your bearing housing deflects more than the bearing radial clearance, the bearing will seize under load. This is the kind of insight Mahindra and Tata Technologies expect from their FEA engineers.

Von Mises Stress — The Standard for Structural Failure Prediction

Von Mises Stress — named after physicist Richard von Mises — is the most widely used criterion for predicting yielding in ductile metals like steel and aluminium. It combines all six stress components into a single equivalent stress value. The rule is simple: if Von Mises Stress exceeds the material yield strength, the part will permanently deform. For structural steel (IS 2062 Grade A), yield strength is approximately 250 MPa. If your simulation shows a Von Mises peak of 312 MPa at a sharp corner, that corner will yield in service — you need to redesign it. A common beginners mistake is looking only at peak stress values at stress concentrations. These peaks are often mesh artefacts. The good news is that ANSYS lets you probe average stress over a region, which gives a more realistic picture.

Factor of Safety: How to Calculate and Interpret It

Factor of Safety (FoS) is the ratio of a material yield strength to the maximum Von Mises stress in your part: FoS = Yield Strength divided by Max Von Mises Stress. A factor of 1.0 means the part is exactly at its yield limit — any additional load will cause permanent deformation. Industry standards typically require FoS of 1.5 to 3.0 depending on the application. Safety-critical components — automotive suspension arms, pressure vessel flanges — may require FoS of 2.5 or higher. You can insert a Safety Factor result directly in ANSYS Mechanical; it generates a colour map where red zones have FoS below your threshold. Companies like Bajaj Auto and Force Motors use this check as a mandatory gate before any part goes to physical testing.

Probes and Path Plots for Precise Data Extraction

Probes are ANSYS tools that extract a precise numerical value at a single point or edge in your model. Right-click on the Solution branch, insert a Probe, select the geometry (vertex, edge or face) and choose the quantity — deformation, stress, strain or reaction force. Path Plots take this further: you define a line through your model (along the centre of a beam, for example) and plot how a quantity varies along that path. This is invaluable for checking if a weld seam sees uniform stress or has dangerous hot spots. Reaction force probes at fixed supports tell you how much load each mounting point carries — critical information for bolt sizing. None of this shows up in colour contour plots alone, which is why probes and paths are what separate a thorough FEA report from a screenshot.

Generating Professional Simulation Reports in ANSYS

A professional ANSYS simulation report should include: a summary of the geometry and loading conditions, mesh statistics (element count, element type, mesh quality metric), a table of applied boundary conditions, colour plots of Total Deformation and Von Mises Stress with the scale bar visible, a Factor of Safety plot with your design threshold marked, probe values at critical locations, and a clear engineering conclusion — does the design pass or fail? ANSYS Mechanical has a built-in Report Generator under the Home tab that automates much of this formatting. What most people don't realize is that a clear, well-structured report is often what gets a mechanical engineer promoted at companies like Bosch India and Siemens India — because it demonstrates engineering communication skills, not just software proficiency.

Common Post-Processing Mistakes and How to Avoid Them

The four most common post-processing errors beginners make. First, reading peak stress at a stress concentration without checking if it is a mesh singularity — refine the mesh at that location and see if the stress converges or keeps rising. Second, ignoring the deformation scale factor — ANSYS exaggerates deformations visually for clarity; always check the actual numerical maximum. Third, using wrong material properties — if Young modulus is entered in Pa instead of MPa, your deformation results will be off by a factor of one million. Fourth, not verifying results with a hand calculation first — for a simple beam, ANSYS should match your textbook formula within 5%. If it doesn't, something is wrong with the model setup. Catching these issues is exactly what our AI Powered Product Design, Analysis and Simulation workshop at ABC Trainings teaches, alongside full ANSYS Workbench training in Pune and Sambhajinagar.

FAQs

What is Von Mises stress and why is it used in ANSYS simulations?

Von Mises stress is an equivalent stress value that combines all stress components into one number, used to predict yielding in ductile metals. If Von Mises stress exceeds the material yield strength (e.g., 250 MPa for structural steel), the part will permanently deform. ANSYS uses it as the default structural failure criterion because it works well for most engineering metals.

How do I calculate Factor of Safety in ANSYS Workbench?

In ANSYS Mechanical, right-click on the Solution branch, select Insert, then Safety Factor. Set your design threshold — typically 1.5 to 3.0 depending on the application. ANSYS generates a colour map where red zones have FoS below the threshold. You can also calculate manually: FoS = Yield Strength of Material divided by Maximum Von Mises Stress from your simulation.

What should a professional ANSYS simulation report include?

A professional simulation report should include: geometry and loading summary, mesh statistics (element count and type), applied boundary conditions, Total Deformation and Von Mises Stress colour plots with visible scale bars, Factor of Safety plot, probe values at critical locations, and a clear engineering conclusion. ANSYS Mechanical has a built-in Report Generator under the Home tab that automates much of the formatting.
