Hi All,

This is UEqn code in icoFoam:

fvVectorMatrix UEqn
        (
            fvm::ddt(U)
          + fvm::div(phi, U)
          - fvm::laplacian(nu, U)
        );

AFAIK,momentum equation can be devided into three components,this three components u v w should be calculated in three algebraic equations,see equation 6.8 and 6.10 in H K Versteeg's book.so why is there only UEqn's matrix?where is VEqn and WEqn?



Thanks in advance.
