Detailed Description

Geometric metadata used to estimate drag reference area.

Area estimation can be explicit (via reference_area_m2) or inferred from a primitive shape. Inferred area depends on velocity direction and orientation for non-spherical shapes.

Member Enumeration Documentation

◆ Shape

enum class frcsim::RigidBody::AerodynamicGeometry::Shape

strong

Primitive shape model used for reference-area estimation.

Enumerator
kCustom	Use only explicit caller-provided area (no shape inference).
kSphere	Sphere model parameterized by radius_m.
kBox	Box model parameterized by box_dimensions_m.
kCylinder	Cylinder model parameterized by radius, length, and axis.

Member Data Documentation

◆ box_dimensions_m

Vector3 frcsim::RigidBody::AerodynamicGeometry::box_dimensions_m {0.0, 0.0, 0.0}

Box dimensions (x, y, z) in meters.

◆ cylinder_axis_local

Vector3 frcsim::RigidBody::AerodynamicGeometry::cylinder_axis_local {0.0, 0.0, 1.0}

Cylinder principal axis expressed in local body coordinates.

◆ cylinder_length_m

double frcsim::RigidBody::AerodynamicGeometry::cylinder_length_m {0.0}

Cylinder length in meters along cylinder_axis_local.

◆ radius_m

double frcsim::RigidBody::AerodynamicGeometry::radius_m {0.0}

Sphere/cylinder radius in meters.

◆ reference_area_m2

double frcsim::RigidBody::AerodynamicGeometry::reference_area_m2 {0.0}

Explicit area override in square meters.

When > 0, this value bypasses shape-based area estimation.

◆ shape

Shape frcsim::RigidBody::AerodynamicGeometry::shape {Shape::kCustom}

Selected shape model.
