Enum BoundaryCondition 

pub enum BoundaryCondition {
    Dirichlet(f64),
    Neumann(f64),
    Robin {
        value: f64,
        alpha: f64,
        beta: f64,
    },
}

A boundary condition for one side of one coordinate axis.

The derivative in Neumann and Robin is taken with respect to the increasing coordinate direction x, not an outward normal. This keeps the Cartesian interpretation unambiguous.

Variants

Dirichlet(f64)

u = value at the boundary.

Neumann(f64)

du/dx = value at the boundary.

Robin

alpha * u + beta * du/dx = value at the boundary.

Fields

value: f64

Right-hand side of the Robin condition.

alpha: f64

Coefficient of the value u.

beta: f64

Coefficient of the derivative du/dx.
