h1. Numerical Solution

The user defined function from the Pre-Analysis section defines the lift function in C and defines the pressure and centroid of each face, then calculates the quantity called liftFunc, defined as

{latex}\begin{eqnarray}
\phi = -psin(\theta)
\end{eqnarray}{latex}

Once the user defined function is implemented, Fluent will use liftFunc as a boundary condition to integrate the specified user defined scalar over the entire specified surface.

User-defined function implementation to obtain the lift coefficient around the cylinder is as follows.
