Artificial viscosity term only for particles nearing one another
The expression for the viscous term above is taken from the wiki at https://github.com/DualSPHysics/DualSPHysics/wiki/3.-SPH-formulation#321-artificial-viscosity
Can a developer please direct me to where this formulation is implemented in the GPU code?
I am essentially interested in looking into this difference between approaching and parting particle pairs. It is a technical question at this moment: knowing how this is done is more important than knowing why. Thanks in advance for directions.

If this is not brash of me to presume who has the topmost view to the source code, I would ask if @jmdalonso would please give some directions. Thanks in advance.
