"We showed how to use SPH, for flows in curved metrics of space. We captured the shocks, and adjusted the clocks. Our tests, they all worked in each case."

— Liptai & Price (2019)

How does this dust collect in protoplanetary discs to form planets like the Earth and people like us? How do stars feed black holes in tidal disruption events? How does the common envelope get ejected?

All of these questions can be answered using Phantom, a smoothed particle hydrodynamics code developed right here at Monash.

It's been a couple of traumatic years since we last met, so it's time to gather the user community together, solve some problems and set some goals


1. To consolidate development efforts

2. To set a roadmap for development priorities

3. To grow the user community, and especially to encourage sideways interaction between users

We will set each afternoon of the workshop as a hackfest, to collaboratively implement new features and tests

Dates: 13th-17th Feb 2023

Venue: Monash University, Melbourne, Australia


A detailed program will be announced after the registration deadline has closed. Each morning will be devoted to invited and contributed talks, with afternoons devoted to collaborative code efforts


The conference will be held in: Room 107 (first floor)
School of Physics and Astronomy
10 College Walk
Monash University Clayton Campus
Clayton, Victoria, Australia.

The cheapest way to get here is to take the Skybus from the airport to Southern Cross Station, jump on a train to Huntingdale (Pakenham/Cranbourne line) and then catch the 601 shuttle bus from Huntingdale station to the campus. Total cost around $25. Check the ptv website for details.

The fastest way to get here is in a taxi, but it will cost you around $120.


Our recommmended accommodation option is Mannix college. Otherwise you can check hotels close to campus. Staying somewhere in South Yarra is another option which is on the train line to Monash (30 mins to campus) but in a lively area closer to the centre of Melbourne.
