Demonstrations

Demonstrations are small, reproducible examples with a declared observable, reference or invariant. They are useful for learning and verification; they do not establish universal element or solver qualification.

Public examples

The maintained JSON examples are in examples/. Choose examples from the same source revision as the solver. The shortest path is the TET4 static quickstart. The public Python API is available through qf_solver.

Evidence-aware demonstrations

Some demonstrations generate a result directory containing inputs, outputs, diagnostics and a manifest. Read the reported residual, reactions, energy and mesh checks together. A plausible displacement alone is not sufficient.

The published 0.2.8 boundaries remain in the historical verification summary. For the cumulative 0.2.11 solver, consult the capability index, V&V summary, the inherited 0.2.10 evidence, and the bounded nonlinear example. Large-model examples are described in Large models.

Experimental rotating-modal and Campbell demonstrations retain their bounded BEAM2/disk scope. GYRO-06 is internal mesh-convergence evidence, not physical validation, and the high-frequency ambiguity at 100 rad/s is preserved.
