Summary and evidence

Evidence of learning

• 01_parametric_beam.mac executed from a clean session.
• m01_design_table.csv with four alternatives.
• Archive the challenge with a fifth alternative.
• Table "defect → symptom → causes → correction" of the bug hunt.
• Prediction and explanation of the 1/8 ratio obtained by doubling the height.

Validation checklist

• I gathered all the physical entries into a documented block.
• I eliminated the magic numbers of geometry, material, mesh, and charge.
• I distinguish entries, derivatives, references and results FEA.
• The script rejects non-positive dimensions and mesh.
• The CSV matches the expected results within tolerance.
• The first valid height of the base assembly is 120 mm.
• I completed the bug hunt and challenge without using the GUI.
