Impact of changing the sinc kernel index n and number of neighbors nb on the pairing-instability during the relaxation towards equilibrium of a perturbed homogeneous system. In the X-axis the minimum interparticle distance normalized to its initial value is represented. The Y-axis shows the corresponding percentage of particles at different times. We show the results for n = 3 (red), n = 5 (green), n = 7 (blue) and n = 10 (pink). Continuum lines are for t = 0.01, dashed lines for t = 0.19 and big dots for t = 1.79. The continuum line in light blue for nb = 100 was calculated using the Wendland C3 interpolator and shows the results at t = 0.19.
