On the roadmap

What it runs on
Finite element stress and modal
What it decides
Peak stress at the notch
Cost of being wrong
A life prediction nobody can defend

What it checksCriterion

  1. 01
    Mesh convergence at the notch

    A peak that has not converged is a mesh result, not a stress result.

    peak stable under refinement
  2. 02
    Nonlinear step accepted early

    An increment that stopped iterating before the equilibrium was found.

    residual below its own tolerance
  3. 03
    Element behaviour

    Modes that carry no stiffness, and elements that carry too much.

    no hourglass, no locking

These are criteria, not results. Nothing here has been measured — the product is not built.

What comes back

  • The cause, and the line of solver output it came from
  • The change, as a diff you can reverse
  • Physics checks, measured against their limits
  • A record somebody else can open on a link

Targets

  • CalculiX (target)
  • code_aster (target)
  • Commercial FE adapters (planned)

Named as intent. No adapter for any of these exists today.

Standing

Not built. The loop is the same one Fluids runs — the work is a parser for solver output, a checker set for these quantities, and a fix whitelist that is safe for a structural model. None of it exists yet.
