Hiiiii,
I'm working on Simulation of two phase immscible flow through porous media. I've oil-water equations to be solved. Oil equation: - fvm::ddt(por,sw) + fvm::Sp(J*n*M_o,p) - fvm::laplacian(phik*phiM_o,p) == - fvc::laplacian(phiM_o*phik*rho_o,gh) + fvc::Sp(J*n*M_o,pbh) Similarly i've equation for water. I want to solve two equations simultaneously. how to solve equations simultaneously by using "solve" . Can any one help how to proceed. Thanks & Regards N.Manjunath Last edited by manju819; February 26, 2014 at 13:19. |

as far as I know, there only possibility to solve two equations at the time, is to use the block coupled solver in foam-extend. The .com and .org versions use solvers for scalars. Even the velocity is solve sequentially.
