Challenge ~4 min · ~10 min remaining

Summary and evidence

Keep the script, comparison CSV, and an explanation of each calculated error.

Evidence of learning

  • m07_validation_audit.csv with entries, references and errors.
  • Manual deflection and stress predictions.
  • Comparison between face mean and corner node.
  • PLNSOL and PLESOL contour plots of S,X.
  • Diagnosis of the five misleading validation approaches.
  • m07_scaling_audit.csv with the reasons for the challenge.
  • POST26 contour and curve PNG generated by 07_graphics_post26.mac.
  • m07_load_response.csv and m07_graphics_slope_audit.csv (expansion).

Exit checklist

  • ☐ I identify and activate the set I analyze.
  • ☐ I declare the results system.
  • ☐ I inspect the deformed shape before examining stress.
  • ☐ My probe represents a physical region, not an ID.
  • ☐ I compare equivalent magnitudes.
  • ☐ I avoid using the singular fixed-support maximum.
  • ☐ I document the averaging method, reference, and tolerance.
  • ☐ I maintain balance and traceability with previous modules.
  • ☐ (Optional) I distinguish POST1 from POST26 and export graphics with metadata.

Technical traceability

The lesson uses Structural Analysis Guide for post processing, Theory Reference for the interpretation of results, Element Reference for the outputs of SOLID185 and Command Reference 2024 R1 for /POST1, /POST26, SET, RSYS, /SHOW, /GFILE, /TITLE, /AXLAB, PLDISP, PLNSOL, PLESOL, PLVAR, PRVAR, NSOL, NUMVAR, PRNSOL, NDNEXT and *GET.

Next step: M08

We already have a model that is built, solved and validated. In M08 we will convert it into a reusable tool using macros, arguments, files and a strategy of systematic debugging.
