Struct salva2d::object::Boundary

pub struct Boundary<N: RealField> {
    pub positions: Vec<Point<N>>,
    pub velocities: Vec<Vector<N>>,
    pub volumes: Vec<N>,
    pub forces: Option<RwLock<Vec<Vector<N>>>>,
}

A boundary object.

A boundary object is composed of static particles, or of particles coupled with non-fluid bodies.

Fields

positions: Vec<Point<N>>

The world-space position of the boundary particles.

velocities: Vec<Vector<N>>

The artificial velocities of each boundary particle.

volumes: Vec<N>

The volume computed for each boundary particle.

forces: Option<RwLock<Vec<Vector<N>>>>

The forces applied to each particle of this boundary object. If this is set to None (which is the default), the boundary won't receive any force for fluids.

Methods

impl<N: RealField> Boundary<N>

pub fn new(particle_positions: Vec<Point<N>>) -> Self

Initialize a boundary object with the given particles.

pub fn num_particles(&self) -> usize

The number of particles of this boundary object.

pub fn transform_by(&mut self, pose: &Isometry<N>)

Transforms all the particle positions of this boundary by the given isometry.

pub fn apply_force(&self, i: usize, f: Vector<N>)

Apply a force f to the i-th particle of this boundary object.

This call relies on thread-safe interior mutability.

pub fn clear_forces(&mut self, resize_buffer: bool)

Clears all the forces applied to this boundary object's particles.
