Poisson::BoundaryConditions::Robin< Dim > Class Template Reference

Impose Robin boundary conditions \(a u + b n_i \nabla^i u = c\). The boundary condition is imposed as Neumann-type (i.e. on \(n_i \nabla^i u\)) if \(|b| > 0\) and as Dirichlet-type (i.e. on \(u\)) if \(b = 0\). More...

Detailed Description

template<size_t Dim>
class Poisson::BoundaryConditions::Robin< Dim >

Impose Robin boundary conditions \(a u + b n_i \nabla^i u = c\). The boundary condition is imposed as Neumann-type (i.e. on \(n_i \nabla^i u\)) if \(|b| > 0\) and as Dirichlet-type (i.e. on \(u\)) if \(b = 0\).
