Jokes aside, I think this is actually one of the powerful aspects of federation. On the corporate sites, the single namespace meant that for #SmoothedParticleHydrodynamics we had to use the #SPH_ tag (with the underscore) to avoid confusion with, shall we say, other uses of the same #SPH acronym.
On the #Fediverse, the experience is more “local”, something that I already observed with the Page42 game (<https://fediscience.org/@giuseppebilotta/113554443204685599>).
This means that, at least within the confines of the servers more focused on science, the unmodified tag has a better chance to work for the numerical method.
(Still, if I browse the tag, aside from feeling a bit “vox clamantis in deserto”, I do see a couple of posts with that other meaning.)
There's something to be said about #Fediverse weirdness, that we all see different things. I discovered the Page42 hashtag game on my "unprofessional" profile, but since I'm at work now and taking a break, I participated by grabbing the closest book I have on hand, which is unsurprising a (somewhat dated, but still valid) reference on #SPH #SmoothedParticleHydrodynamics —and that seems to actually be quite characteristic of _this_ corner of the Fediverse 1/2
There will also be 4 special sessions,
https://spheric2025.upc.edu/index.php/call-for-special-sessions/
for #Aerospace and maritime applications, #SolidMechanics, #CoastalEngineering (an #SPH classic), and one focused on #RenewableEnergy modelling and innovations through #SPH
#SPH_ #SmoothedParticleHydrodynamics

Let's talk about #SmoothedParticleHydrodynamics (#SPH for short, even though you'll see #sph_ used on other sites, because #SPH also has a very common, very not-safe-for-work meaning …).
Why should we talk about it? Because it's relatively less known than other numerical methods, possibly undeservingly so, and because I love it.
So what is it? SPH is a Lagrangian meshless numerical method primarily used for #ComputationalFluidDynamics (and more recently also #ComputationalMechanics).
