buffalo_panel.post.PanelSolution2D

class buffalo_panel.post.PanelSolution2D(geometry, freestream, strengths, surface, integrated, _velocity_evaluator=None, _potential_evaluator=None, _stream_function_evaluator=None)

Post-processed solution for a two-dimensional panel calculation.

This object groups the information most users need after a solve: the geometry and freestream context, formulation-specific strength fields, solver-agnostic surface quantities, and integrated aerodynamic coefficients. Field quantities such as velocity, potential, and stream function are expected to be computed on demand by future solution methods rather than stored here by default.

Methods

potential_at(points)	Evaluate velocity potential at field points.
pressure_coefficient_at(points)	Evaluate pressure at field points.
stream_function_at(points)	Evaluate stream function at field points.
velocity_at(points)	Evaluate velocity at field points.

Attributes

geometry	Geometry used to produce the solution.
freestream	Freestream state used to produce the solution.
strengths	Solved singularity-strength fields associated with the solution.
surface	Surface flow quantities recovered from the solved strengths.
integrated	Integrated aerodynamic coefficients recovered from the solution.
