Struct PySphBinding 

pub struct PySphBinding { /* private fields */ }

PyO3-style binding handle for a 3-D SPH simulation.

Uses the PySphSim type (WCSPH) defined earlier in this file.

Implementations

impl PySphBinding

pub fn new_water() -> Self

Create a new SPH binding with the water-like default configuration.

pub fn from_config(config: PySphConfig) -> Self
