Struct RobinBC 

pub struct RobinBC<S: Scalar> {
    pub alpha: S,
    pub beta: S,
    pub gamma: S,
}

Robin boundary condition: αu + β∂u/∂n = g at the boundary.

Fields

alpha: S

Coefficient for u

beta: S

Coefficient for ∂u/∂n

gamma: S

Right-hand side value

Implementations

impl<S: Scalar> RobinBC<S>

pub fn new(alpha: S, beta: S, gamma: S) -> Self

Create a Robin BC: αu + β∂u/∂n = γ.

pub fn convective(h_over_k: S, u_ambient: S) -> Self

Create a convective BC: h*(u - u_ambient) = -k*∂u/∂n. This is equivalent to: (h/k)*u + ∂u/∂n = (h/k)*u_ambient.
