I want set adiabatic condition of the wall to the environment. However, in the thermal condition panel of fluent for the wall, there are several options like : heat flux, temperature, convection, radiation, mix.&nbsp;<\/p>\n<p><\/p>\n<p>I am wondering if I set the heat flux or convection coefficient to 0 in order to indicate adiabatic condition to environment. How does the heat produced on the wall transfer to inner gas flow. Because the heat flux on the wall is zero or the convection coefficient of the wall is 0. No heat flux is going to happen along the wall nodes.<\/p>\n<p><\/p>\n<p>below is my mesh.
