Five convincing results

Identify singularities, isolated nodes, incorrect result sets, and comparisons at the fixed support.

Bug hunting — Five convincing results

  1. Implicit set: results are queried without knowing which set is active.
  2. Fixed ID: numerical identity is confused with physical location.
  3. Different magnitudes: von Mises is compared with normal stress.
  4. Singular maximum: the fixed-support stress governs the entire conclusion.
  5. Hidden transformation: neither RSYS nor the averaging method is declared.

For each case, identify the number that might seem reasonable, the physical question that number actually answers, and the evidence that is missing.

Quick check

The maximum stress appears at the fixed support. Is it the appropriate quantity for validating the beam?

Professional incident

Incident M07: diagnose before editing

The plotted maximum and validation probe use incompatible locations.

Execution cycle

  1. 1 Run the broken script in a clean folder.
  2. 2 Preserve the original .out.
  3. 3 Write one causal hypothesis and make one change.
  4. 4 Compare evidence before and after.
Evidence to retain

Graduated hints

1 · Concept hint

Find the first broken contract.

2 · Command hint

Inspect state related to PLNSOL, PLESOL, and ETABLE.

3 · Explained solution

Compare with the module deliverable and explain why the corrected state restores the contract.
