  Hi everyone . I want to know if I want to include the internal emissivity and external emissivity numbers in Fluent they should be similar, I went to the help section of Ennis and there is just explained that the two are different with each other and not explained that how they should work. When I look for material emissivity only gives me for one emissivity. I will glad if You help me. Thank you in advance for guiding&helping me
