Detailed Description

Robin boundary condition. This type of boundary condition doubles for any boundary condition of the form

\[ a \phi + b D \hat{n}\cdot \nabla \phi = f \]

When $ a=0$ the boundary condition is equivalent to a Neumann boundary condition.

\[ b D\hat{n}\cdot \nabla \phi = f \]

When $ a=\frac{1}{4} $, $ b=\frac{1}{2} $ and $ f=0 $ then the boundary condition is equivalent to a Vacuum boundary condition.

\[ \frac{1}{4}\phi + \frac{1}{2}D\hat{n}\cdot \nabla \phi = 0 \]
