Struct NBodySolver 

pub struct NBodySolver {
    pub use_tree: bool,
    pub theta: f64,
    pub softening: f64,
}

N-body gravity solver.

Fields

use_tree: bool

Use Barnes-Hut tree approximation.

theta: f64

Barnes-Hut opening angle parameter.

softening: f64

Softening length to prevent singularities (m).

Implementations
