- embedded3 DeviceStep::snapshot/restore (step/device/snapshot.rs): the start-of-step
device fields + the moving body's host records; a restore rebuilds the R6 persistent
geometry/classification, the predictor tables, the hierarchy and the guess basis.
Only called by the new harness (existing paths untouched).
- exchange::set_load_sink: every contribution of the operator load route (p W, wall
shear, diffusive/convective exchange) with position/component/part; None by default,
the routes' sums unchanged (slab ny 62 CSV byte-identical to r6_1/base_slab62.csv).
- rtx-fsi feature cuda (= rtx-cfd/cuda) and tests/fsi2_embedded3.rs: the 2D rtx-fea flag
(35x2 Quad8, TL, Newmark 0.7) drives the capsule's centreline per coupled step; the
route's contributions are distributed onto the wetted nodes per unit span; Aitken
subiterations each re-run the fluid step from the snapshot.
