buffalo_panel.geometry.ThinBodyLineGeometry2D

class buffalo_panel.geometry.ThinBodyLineGeometry2D(x, y, *, geometry_id=0, geometry_name=None, point_element=True)[source]

Bases: BaseBodyLineGeometry2D

Line-panel geometry representing a thin-body camber-line discretization.

Panels lie on the body reference curve. The intended default convention is quarter-panel element placement with three-quarter-panel collocation, though the shared stored fields remain the same as the thick-body geometry.
