Energy equation in Fluent
Fluent solves the following equation for non-isothermal single phase simulation involving gas flow in a duct:

According to Fluent manual: "Under the assumption that the Lewis number (Le) = 1, the conduction and species diffusion terms combine to give the first term on the right-hand side of the above equation while the contribution from viscous dissipation appears in the non-conservative form as the second term."

My question is where is the second term? The second term is the energy source term.
