go.Figure	plot_chamber_geometry_clear (Dict[str, np.ndarray] geometry, Optional[PintleEngineConfig] config=None)

Detailed Description

Clear chamber geometry visualization showing the actual structure.

Structure:
- Gas boundary (inner surface where hot gas flows)
- Ablative liner (chamber region, NOT throat)
- Graphite insert (ONLY at throat region, small axial length)
- Stainless steel case (outer structure)
- Nozzle (diverging section after throat)

- L_chamber to L_chamber+L_nozzle: Nozzle (diverging, can be ablative or other)

Parameters:
-----------
L_chamber : float
    Chamber length [m] (from injector to throat)
D_chamber : float
    Chamber inner diameter [m]
D_throat : float
    Throat diameter [m]
L_nozzle : float
    Nozzle length [m] (diverging section after throat)
expansion_ratio : float
    Nozzle expansion ratio (A_exit / A_throat)
ablative_config : AblativeCoolingConfig, optional
    Ablative configuration
graphite_config : GraphiteInsertConfig, optional
    Graphite configuration
recession_chamber : float
    Cumulative ablative recession [m]
recession_graphite : float
    Cumulative graphite recession [m]
n_points : int
    Number of points for geometry

Returns:
--------
geometry : dict
    - positions: Axial positions [m]
    - R_gas: Gas boundary radius [m]
    - R_ablative_outer: Ablative outer radius [m] (chamber region only)
    - R_graphite_outer: Graphite outer radius [m] (throat region only)
    - R_stainless: Stainless steel outer radius [m]
    - R_nozzle_gas: Nozzle gas boundary radius [m]
    - throat_position: Throat axial position [m]
    - graphite_start: Graphite insert start position [m]
    - graphite_end: Graphite insert end position [m]
