Hello Dear Foamers,

I apologize if this question which may have been answered before but I can't figure out yet how to solve this issue.

I am trying to modify the momentum equation by adding a source term such K*U but I would like to model this constant (K) as a tensor (Matrix 3X3). Any idea how to perform this ? Also, how will OpenFoam deal with this ? as far as I know, it solves in a segregated manner so :
will it solve implicitly for one componenet of the velocity and used explicit values for the rest ?

and finally

where Kij is the component of the tensor, n is the iteration number and Up,Vp and Wp stands for the velocity components at the specified cell / control volume.

Also, I will be highly grateful if anyone can let me know where in the documentation or links to find the detailed way openFoam calculates the ap and H(U).
