AxisymmetricBody

final class AxisymmetricBody

Bases: _VolumeEntityBase

Generic body of revolution, represented as (axial, radial) profile polyline with arbitrary center and axial direction.

First and last profile samples must connect to axis (radius = 0), and the segment touching each endpoint must be perpendicular to the axis so the body closes with a flat cap (the endpoint shares its neighbor’s axial coordinate). The two caps must sit at distinct axial coordinates so the body has non-zero extent; the interior polyline between them is arbitrary. Cone-like apexes tapering to a point on the axis are not supported.

Example

>>> AxisymmetricBody(
...     name="cone_frustum_body",
...     center=(0, 0, 0) * unyt.inch,
...     axis=(0, 0, 1),
...     profile_curve=[
...         (-1, 0) * unyt.inch,
...         (-1, 1) * unyt.inch,
...         (1, 2) * unyt.inch,
...         (1, 0) * unyt.inch,
...     ],
... )
