Jasak is rite, its a kind of semi-discretised form of equation. the pressure gradient is not discretised at this stage.

I think its not correct, it should be:

{a_p}{u_p} = \sum {{a_n}{u_n} - \nabla p_f}

While it does not matter..do you think so?

Jasak's Ueqn.

Hi guys,

\begin{array}{l}
{a_p}{u_p} = \sum {{a_n}{u_n} - \nabla p,} \\
{a_p}{u_p} = \sum {{a_n}{u_n} - \int {\nabla p} dv}
\end{array}

The first one in the famous Ueqn in Jasak's...
