Struct salva2d::solver::IISPHSolver

pub struct IISPHSolver<KernelDensity: Kernel = CubicSplineKernel, KernelGradient: Kernel = CubicSplineKernel> {
    pub min_pressure_iter: usize,
    pub max_pressure_iter: usize,
    pub max_density_error: Real,
    /* private fields */
}

A IISPH (Implicit Incompressible Smoothed Particle Hydrodynamics) pressure solver.

Fields

min_pressure_iter: usize

Minimum number of iterations that must be executed for pressure resolution.

max_pressure_iter: usize

Maximum number of iterations that must be executed for pressure resolution.

max_density_error: Real

Maximum acceptable density error (in percents).

The pressure solver will continue iterating until the density error drops bellow this threshold, or until the maximum number of pressure iterations is reached.
