buffalo_panel.geometry.ThickBodyLineGeometry2D

class buffalo_panel.geometry.ThickBodyLineGeometry2D(x, y, *, geometry_id=0, geometry_name=None)

Bases: BaseBodyLineGeometry2D

Line-panel geometry representing a thick-body boundary discretization.

Panels lie on the physical body surface and collocation points represent boundary-condition enforcement locations on that surface.
