Hi everybody,

Could someone tell me what div(phi,U) means in sonicFoam.C, is it the divergence of the scalar product between phi and U ? or is it something else?

Thanks for your help

No. Its the divergence of the vector field U. YOu just need phi to work it out in the FVM

Hi Gavin,

Is it the same thing in simpleFoam.C for you?
I mean do you think that "div(phi,U)" is just div(U)??

Because, I thought that div(phi,U) is always something like div(UU).

Am I wrong???

Hi,

After thinking about it, I think that div(phi,U) is the divergence of the tensor rho*Ui*Uj.
