The current theory predicts failure by mean of a dimensionless ∏ ratio which is explained on this page: Appendix pdf - Equations etc. . When this ratio is less than one, then the effluent turbidity should be above 0.25 NTU and this means that the spacing for a given flow rate is going to be above the maximum allowed turbidity.

The code works on a Velocity-Verlet algorithm which computes all particles paths based on their experienced local velocities. The code takes particles sizes and the tube (or plate) geometry as well as the up flow velocity as an input. The figure below summarizes the steps taken by the algorithm.
The output of the program is the number of particles that were not captured and their respective paths.
Further Developments
The team plans to adjust some of the parameters in order to be able to (at least roughly) compare the results and predictions of the numerical model with the experiments.
