Function Documentation

_configured_convergent_half_angle_rad()

float backend.routers.geometry._configured_convergent_half_angle_rad ( config )

protected

Convergent half-angle [rad] from design_requirements, else the 45 deg default.

The drawn contour used to be pinned at 45 deg while Layer 1 optimised against
``layer1_contraction_half_angle_deg``, so the geometry tab and the DXF showed a
chamber that was not the one being scored.

_jsonable()

backend.routers.geometry._jsonable ( v )

protected

NaN and inf are not JSON: they go out as null.

get_chamber_geometry()

backend.routers.geometry.get_chamber_geometry

(

UserSession

session = Depends(get_session)

)

Get chamber geometry for visualization.

Returns the geometry arrays needed to render the chamber cross-section:
- Gas boundary (inner surface)
- Ablative liner (chamber region)
- Graphite insert (throat region)
- Stainless steel case (outer)

get_injector_layout()

backend.routers.geometry.get_injector_layout

(

UserSession

session = Depends(get_session)

)

Face, passage and back-face geometry of the session's impinging injector.

Definition at line 411 of file geometry.py.

References _injector_layout_or_404().

get_injector_spray()

backend.routers.geometry.get_injector_spray	(	bool	sensitivity = True,
		UserSession	session = Depends(get_session) )

Spray and mixing report of the session's impinging injector at its own tank pressures
(engine/core/injectors/spray_report.py). Solves the engine, and with ``sensitivity`` once more
per open input (~20 s): a plain ``def`` so FastAPI runs it off the event loop.

post_injector_layout()

backend.routers.geometry.post_injector_layout

(

dict

body

)

The same, for a config the caller holds (e.g. a Forward-mode result's config).

Takes ``{"config": {...}}`` as a plain dict and needs only the injector, chamber
diameter, discharge and design-requirements sections -- no full validation, so a
partial config still draws.
