I have the robin bc --- u(1,t) + 2u_x(1,t) = 0, t>0. What is the physical meaning of the boundary condition?

No flux boundary conditions (i.e. ) says there is no flow of heat - insulated. So saying is saying the flux is proportional to the heat - the larger the heat the larger the flow.
so if u(1,t) <0 then flux >0 which means heat is flowing into the rod?
