About Radiation Boundary Condition
 

Hi,
I am solving transient heat conduction problem, now I want to apply the following boundary condition-
k*dT/dn = h*(T-Tinf)+(sigma*emissivity)*(T^4-Tinf^4)
I have already applied the robin boundary condition for convecting cooling by the help of groovyBC. Now I am wondering with the radiation term.... Does anyone have idea ?
Thanks in advance.....
