Hi Adam, Sorry for the slow reply. Just to follow up, this does now work in the latest version. Just use
--sink=1 (where 1 is the number of the sink particle you want to centre on) or --origin=3427 (to centre on a regular particle) There is also a similar flag, --track=3427 to have limits follow a particular particle (which does not recenter the coordinates). Finally you can also use the following to always centre on the maximum density particle: --origin=maxdens For example you can make the plot you requested from the command line using: splash -r density -vec v --origin=3427 Cheers, Daniel > On 20 Jan 2023, at 8:32 pm, Adam Fenton <xxx> wrote: > > Hi Daniel, > > I have a quick splash question regarding velocity vectors.
