A User Defined FLUENT script (UDF) was created to extract the G_theta value from the flocculator. The UDF loops through all of the individual cells of the converged solution, and extracts the energy dissipation^1/2 times the cell area. The sum of this quantity for all cells divided by flow and square of viscoisty results in the G_theta value of the entire flocculator as shown in equation 1.

   Gθ_baffle=1/Q*vis^(-1/2)*∑(ε^(1/2)*cell_area)   Eq. 1

...

The above formulation has been determined (with Monroe's help) by weighting the value of Gθ by volume.
