On my way to @spheric2025 ! Would @ddcampayo bring something funny like ddcampayo.github.io/SPHeric_…?

hey @spheric_, sheep obviously follow the equations of weakly compressible SPH!
SheePHydrodynamics to be precise...

(btw, that was not an SPH code, but it shows a typical iterative inner loop.)
(3) improvements / quality of results.
Stable stimulations, specially when combined with particle-shifting, for a quite violent frontal shock between two fluids

But, notice "the usual rules of calculus" must be satisfied. This means that the time integration should be accurate.
2) applicability / expected impact.
Implementing an implicit time integration scheme is not too hard. Many existing codes could use this idea

(1) Novelty
Spatial discretization in SPH has been extensively researched, but time integration has received much less attention. We here show how it directly impacts energy conservation. E.g. appendix B shows a remarkable identity
