Tranport Eqn

Tobi · October 8, 2012, 06:43

Hey all Foamers,

i have a simple question. If I implement a normal and easy transport equation like that one:

Code:

fvm::div(phi,H)
- fvm::Sp(fvc::div(phi), H)
-fvm::laplacian(turbulence->mut()/sigmat, H)

and define two inlets with

Inlet1: -1e6
Inlet2: -1e4

Then the values of the scalar H should be like that:

-1e6 <= H_cell <= -1e4

Is that correct?

Thanks Tobi

Yes it is.
After switching my Schemes to upwind the values are in that range again.
