Units in scalartransportfoam
 
Hello,

I'm wondering about the dimensions of DT in scalartransportfoam.
The wiki says the diffusion coefficient is divided by the fluid density,
but in constant/transportProperties the dimensions are set to be
Code:

DT [0 2 -1 0 0 0 0]
which would indicate that the ordinary diffusion coefficient is used.

Am I overlooking something?

Thank you in advance

Its the same as nu, ie mu/rho.
