how to add a new equation for solving rhoT?

Maanieh.h · June 1, 2014, 15:30

Hello,

I want to solve this simple equation for a simple test case :

$\frac{d(rhoT)}{dt}$ $\pm$ $\nabla$ rho.u.T=0

where the velocity is explicitly introduced ( simply the velocity is a vector (1,0,0) all over the domain.
How can I introduce this velocity to the solver, and what solver to use ? ( I used IcoFoam but i dont know how to deal with the velocity.)

I think you should check "scalarTransportFoam".

Refer the link for more detailed information:

Best Luck!
