On Navier-Stokes Brinkman equations for Porous Media
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 ? i.e, K11*Up(n+1)+K12*Vp(n)+K13*Wp(n) then K21*Up(n+1)+K22*Vp(n+1)+K23*Wp(n) and finally K31*Up(n+1)+K32*Vp(n+1)+K33*Wp(n+1) 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). Respectfully, -Omar |
