Hi Foamers,

I have a question about the best way to represent a term in the fvSchemes dictionary. In particular, In my problem I have to calculate the divergence of a tension field (a volume tensor field). Naturally, I place it the divSchemes dictionary, but when i tried to do

div(tension) Gauss upwind;

I got an EOF error. I added phi, to represent flux, in the form

div(tension) Gauss upwing phi;

and it works but the simulation blew. I check the tutorial files and I see that in Xoodles and buoyantFoam similar terms where represented by Gauss linear.

Is this the right option for this type of term. Can someone help me out?
