Okay this is a general question...how are relativistic fluids handled in the Einstein Toolkit? Yup, overly broad I know. So more specifically,
o Are there good reviews, references, or lectures that describe how we currently handle fluids? For the different models?
o I gather we have several models/codes: GRHydro and IllinoisGRMHD, so resources on those would be much appreciated.
o And initial data readers exist for the LORENE (1 and 2?) and for the FUKA data...resources there might be helpful too.
I am hoping for some introductory information (a review would be great) on all our fluid codes, as well as other codes used in other numerical relativity systems.
Some context: I rub elbows with mathematicians who work in relativisitic fluids (ideal, viscous, etc) and they do not believe that any codes out there can do fluids "correctly." I am trying to understand what we do in the Toolkit and also what they expect "correctly" (my language) to be.
thanks for any help, bill e.g.
Hi Bill,

There are introductory lectures typically given at the Einstein Toolkit Schools and Workshops in the EU and USA. Some of these should have been recorded. You may try to have a loot at the ETK YouTube channel: https://www.youtube.com/@einsteintoolkit/videos

There are also a couple of reviews on Living Reviews that describe the methods that are also used in the Einstein Toolkit hydro codes: special relativity: https://link.springer.com/article/10.1007/lrca-2015-3 general relativity: https://link.springer.com/article/10.12942/lrr-2008-7
Cheers, Bruno
Bruno and Samuel, thanks for all the references...lots to absorb, as expected:)
