Analyses#
Each analysis-type chapter answers the same five questions:
When to use this analysis — what problem class it solves, when to pick it over its siblings.
Boundary conditions and loads — what BCs / load types feed into it, with cross-references to Boundary-condition pitfalls.
The math — one paragraph, with a link to the full theory chapter under Theory.
Running the solve — the high-level
Model.*_solve()call and the result object it returns.Common gotchas + post-processing recipes — links into the focused gallery and the troubleshooting flowchart.
Pick the analysis type that matches your engineering question:
\(\mathbf{K}\, \mathbf{u} = \mathbf{f}\) — the workhorse for >80 % of structural design. Snapshot of displacement / stress / reaction under fixed loads.
Natural frequencies and mode shapes. The
n_modes for a downstream response-spectrum
analysis usually comes from the cumulative
effective-mass curve here.
Steady-state response to sinusoidal forcing across a frequency sweep. FRF curves for vibration-isolation / control-system design land here.
Time-history response under arbitrary time-varying loads. Newmark-β implicit integrator; modal- superposition variant on the planned roadmap.
Modal analysis on N-fold rotationally-symmetric structures (rotors, vaned diffusers). Recovers the full-rotor spectrum at sector cost.
Linear bifurcation buckling load multiplier. Not yet shipped — see the page for workarounds today.
