p.norouzi.gv is on a distinguished road
Hi all, In the ANSYS FLUENT, the units for diffusivity are kg/(ms) while the conventional units for diffusivity (m^2/s). so it means that Fluent is solving *

I have to solve this equation dC/dt= D div(div C)+ s . If*I multiply all the parameters with rho the current equation will be:
d(rho*C)/dt= D div(div roh*C )+ s*rho. I was wondering if it is the correct way to change my equation to the fluent format.




thanks in advance for your help.
