Radiation Boundary Conditions
Solve a PDE with a nonlinear Neumann boundary condition, also known as a radiation boundary condition . The heat flux over the surface is modeled as the emissivity (view field) times the Stefan–Boltzmann constant times the fourth power of the temperature .
Specify a region.
Set up the equation and radiation boundary condition with a term.
Set boundary conditions and solve the equation.
Visualize the solution.
