Hydro Code

-------------------------------------------------------
File			Explanation

VH1+1.cpp		Main Code source file
GJE.cpp			Gauss-Jordan elimination code for matrices
paramreader.cpp		Reads actual run parameters from params.txt file
params.txt		Hydro Code parameters (documented)
diags.cpp		Diagnostic routines
idEOS.dat		ideal equation of state
qcdIEOS.dat		QCD equation of state, from hep-ph/0603048
vh			this is the executeable code
-----------------------------------------------------
Compilation:

On a standard Linux machine, you should be able to type 'make'
and get an executeable file vh. Don't know about other OS, but
who wants to use other OS anyways?

-------------------------------------------------------

Running the code

Having compiled the code, it should run when you type in

./vh

To change lattice size/hydrodynamic parameters, see params.txt

However, you should create the subdirectories

data

and 

data/snapshot

in order for the code to be able to output something useful.
See below

----------------------------------------------------------

Data output will created a file

freezeout.dat 

in data/

which contains the information on the freeze-out surface. It has
the following format:

#radius_in_fm	#time_in_fm/c	#u^t  #u^r  #Pi^r_r/(e+p) #Pi^eta_eta/(e+p) #p 
and 4 more numbers that probably are not important to you (if you're 
interested, see outputMeasurements routine to find out what they are

in snapshot/
you will find snapshots of the temperature profile, energy density profile,...
at given intervals in proper time
