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.
