ars511 is on a distinguished road
How can we modify energy equation in Fluent to take the non Fourier conduction effect into account?
As you know, non Fourier heat conduction equation has one more term( second derivative of temperature with respect to time) than Fourier conduction equation. how can i add this term into the default energy equation.

You could add it as a non-linear source/sink term, but it would be an explicit term and solving this isn't the same time-integration a la the temporal discretization.

It's easier to add new terms in OpenFOAM. Not so easy in Fluent.
