Many times u on the boundaries will be specified as a constant value. In this case, the Dirichlet condition physically corresponds to the situation in which the ends of the vibrating string are held fixed at a constant position. WebTraditionally, the Robin condition is a relation between a quantity T (temperature, velocity, etc.) and its derivative ∂ T / ∂ x n, where x n is directed normal to the boundary. The homogeneous Robin condition can be written ∂ T / ∂ x n + R T = 0 at the boundary (sometimes R ^ ∂ T / ∂ x n + T = 0 is used). scool shooting reaction
