| beam | Beam: free-free ends in the page (Ends 'free'; rigid part of strikes removed and reported; mode displays by Modes.count; bending offsets for ghost and Lyapunov shadow; drawing without supports) | |
| common | Driven plate: spectrogram of the displacement at a listening point (click the plate to move it), whole run, log frequency in driven pitches, per-time or whole-run colour, mode pitch ticks; shared FFT exported | |
| double-pendulum | Spectrogram: log frequency axis by default with a 'log f' chip for linear; rows show the loudest bin in their band; mode lines decided per line | |
| driven-plate | Driven plate: listening (records displacement, velocity, acceleration at the listening point, 512 per period; plays back from any time at a set pitch while the run computes; steady or fixed level; start and playhead marks on the time charts); spectrogram follows the chosen signal; ramp-rate slider; target up to 1e3 E_nl | |
| fput-chain | Anti-alias filter for rendered notes (beam, fput-chain): 4x oversampling, Kaiser FIR low-pass to 0.42 fs, decimation; beam warning now says modes above the passband are filtered out | |
| plate | Plate: remove the curvature (domed rest shape) and its cross-section, to keep the plate simple; Parameters stays in the right column | |
| index.html | Driven plate: new app, rectangular simply supported von Kármán plate driven in one mode (modal force in phase with the mode's velocity, energy-target controller on a log ramp), height map, energy chart, perturbation option | |
