-The current state allows also to validate our simulation and produce quantitative results with a post-process callback. \autoref{fig:beam_y_deflection} shows simulation results of TrixiParticles.jl (on the left) and [@DualSPHysics] (on the right) compared against a reference value of [@Turek:2007]. The curves show the y-deflection of the tip of a beam oscillating under its own weight. The different colors indicate different resolutions in the simulation. The results obtained with TrixiParticles.jl match perfectly those of [@DualSPHysics].
