buffalo_panel.views.LineFamily2DView

class buffalo_panel.views.LineFamily2DView(geometry, family, local_coefficients, kernel, top=True)[source]

Bases: Generic

Diagnostic field view for one line-element family.

The view evaluates velocity, potential, and stream-function contributions by combining family-local unit-influence blocks with an explicit vector of family-local coefficients. This makes the view layer compatible with constant, shared, and future higher-order families without assuming one scalar strength per panel.

Methods

`field_at`(x, y)	Evaluate velocity, potential, and stream function together.
`potential_at`(x, y)	Evaluate induced velocity potential at field points.
`stream_function_at`(x, y)	Evaluate induced stream function at field points.
`velocity_at`(x, y)	Evaluate induced velocity at field points.

Attributes

`geometry`	Geometry containing the family source panels.
`family`	Element family defining panel ownership and local coefficient layout.
`local_coefficients`	Solved or user-specified family-local coefficients.
`kernel`	Kernel used to evaluate family-local unit influence blocks.
`top`	Branch-side convention for points on panel cuts.
