Yesterday was the last day of #SPHERIC2025. Huge thanks to the local organizing committee for their hard (mostly behind the scenes) work, and all the #SPHERIC community for the enjoyable #conference and #unconference. A special thanks goes to Corrado Altomare, chair of the local organizing committee, who delivered a touching speech on the role that #science plays in uniting people beyond #borders and #conflicts, a much needed beacon of hope in the current international outlook.

I'm preparing the next issue of the #SPHERIC newsletter (BTW have you submitted an abstract for #SPHERIC2025 in #Barcelona yet?‌ Deadline is next monday), and the first contribution is about #SPHERIC2024Zhuhai. The organizer sent me so many photos that I'm sad I can't just throw them all in, and I'm having troubles making a good selection. But alas contributions are limited to two pages.

When this post https://mastodon.social/@coreyspowell/113807316007617909 by @coreyspowell popped up in my feed just now my first thought was: «wait, I'm pretty sure I saw something similar at a recent #SPHERIC conference» so of course I checked the linked paper (<https://www.nature.com/articles/s41561-024-01612-0.epdf?sharing_token=9Q4L9YJs0dXIOXIb7dJ9F9RgN0jAjWel9jnR3ZoTv0NvCuY-CCmAUDS-e_nTUnvNU1gexpN1yz5LgFWb6OYeZtFJos0bQQeDtkY5TswjWh9TsZvZ6a44fcxf1Kw-c1KkueYZqv6G1Lx7wrnS7EBY4v1kIZ-srQuT1Md7nJKtojM%3D>) and lo and behold, they do use #SPH #SmoothedParticleHydrodynamics

However, I had a feeling it wasn't exactly the same, and by digging deeper in my memory, I realized that indeed what I had seen wasn't (a preview of) this work, but a #SPHERIC2019 contribution about simulating impacts on planetary giants with #SWIFT (a well-known SPH code for #astrophysics, the field SPH was originally designed for, available from <https://www.swiftsim.com>) with Uranus as a test case. You can read the full article here:

#SPHERIC2025 will be in #Barcelona
https://spheric2025.upc.edu/

It will be the first #SPHERIC #conference to break from the "classic" SPHERIC International Workshop format that was also employed for the SPHERIC 2022 I organized in Catania, and closer to other more traditional conferences (hence also the change in name, to SPHERIC World Conference).

Tomorrow I go to #Berlin for #SPHERIC2024. See you there if you're coming.

P.S. I hate #traveling. The day we invent teleportation can't come too soon.

#SPHERIC #SmoothedParticleHydrodynamics

#SPHERIC2024 abstract submission deadline has been extended to Friday, January 26th. If you or someone you know have a result that may be of interested to the #SmoothedParticleHydrodynamics community, consider submitting it at the upcoming #SPHERIC International #Workshop in #Berlin

While I was away for #SPHERIC, they delivered a couple of new workstations to the office, so today I spent some time setting one up, installing the OS, checking it matched the specs and testing the hardware. One thing I hadn't realized when we ordered this one is that in addition to the NVIDIA GPUs it would also give access to the integrated AMD‌ GPU. This is, I think, my first system where I have hardware from both vendors (although of very different class).

And it's not even that I don't want to talk about it, I do! Not only there were some very interesting results presented that I would like to mention and possibly talk about (it'll only be a selection, sorry, I hope if other #SPHERIC contributors see my posts they don't get offended for not being mentioned), but there are also some important news that involve me directly and which I'm thrilled about (even though they mean even less free time …)

For a more hands-on learning experience, the upcoming 16th #SPHERIC International Workshop <https://www.spheric2022.it> offers a #TrainingDay fully dedicated to learning the basics of #SmoothedParticleHydrodynamics, from the theory to practical examples with a #FreeSoftware #OpenSource implementation.

The community of researchers and industrial users of #SmoothedParticleHydrodynamics is represented by #SPHERIC, an #ERCOFTAC #SIG with the objective of fostering the development of the method and its adoption <https://spheric-sph.org>.
#SPHERIC defined 5 #GrandChallenges for #SPH:
GC1: #convergence, #consistency and #stability
GC2: #BoundaryConditions
GC3: #adaptivity
GC4: Coupling to other models
GC5: Applicability to #industry

There's a lot to learn, and a lot to research, on #SmoothedParticleHydrodynamics. The #SPHERIC Global Seminars <https://www.spheric-sph.org/global-seminars> cover many interesting aspects of the method and its applications, and are an excellent way to whet your appetite and pique your interest.
