Challenge ~4 min · ~10 min remaining

Summary and evidence

Keep the script, equilibrium CSV, and an explanation of reactions and moments.

Evidence of learning

  • m06_equilibrium_audit.csv with passes=1.
  • Extract from .out confirming a finished solution.
  • Manual calculation of RFY and RMZ.
  • Explanation of the sign convention relating RF and FSUM.
  • CSV of the challenge with two states and ratios equal to two.
  • Reasoned diagnosis of the five defects.

Exit checklist

  • ☐ I declare the type of analysis and the geometric hypothesis.
  • ☐ I restore all selections before solving.
  • ☐ I check that a set exists before consulting results.
  • ☐ I consciously activate the state I want to audit.
  • ☐ I add reactions exclusively in the fixed component.
  • ☐ I check force and moment with respect to the same point.
  • ☐ I am not looking for non-existent rotational reactions in SOLID185.
  • ☐ My CSV preserves inputs, results, errors and decision.

Technical traceability

The lesson uses Structural Analysis Guide and Basic Analysis Guide for static solution flow. The syntax of ANTYPE, NLGEOM, KBC, NSUBST, OUTRES, SOLVE, SET, SPOINT, FSUM, NDNEXT and *GET is contrasted with Command Reference 2024 R1.

Next step: M07

We already know that the model solves and satisfies equilibrium. In M07 we will ask something else demanding: if its displacements and stresses correctly represent the physical beam, comparing them with an analytical solution.
