Hi, guys, I have a question when I add temperature equation to icoFoam.
By OpenFOAM Wiki, it's said that, we need to add a new transport property related to the thermal diffusion, like ' DT [0 2 -1 0 0 0 0] 0.002;'
Actually, it is thermal conductivity. But I'm really confused, why it has the same unit as the kinematic viscosity?

Cheers!

Study the equations again. DT is as stated thermal diffusivity, and as any other diffusivity it has units m2/s.

Oh...My fault...It's not conductivity.
Thank you very much!!!!!
