==================

A simple modification to Gadget-2.0.7 (available from [here](https://wwwmpa.mpa-garching.mpg.de/gadget/)) that adds some things that are useful for non-cosmological simulations of single galaxies in a separate environment. Currently this adds

+ A fixed dark matter potential based on a NFW profile.

+ A custom equation of state based on the work of Martizzi (2016).

This is implemented through the following compiler options:

+ DFIXED\_POTENTIAL: switches on the fixed potential

+ DNO\_SELF\_GRAVITY: removes all self gravity (it is still calculated, though, so this does not offer any considerable speedup -- this should be fixed in the future)

+ MARTIZZI\_EOS

You will need to add the following things in your paramter file (we sugguest using the initial conditions generator [here](https://www.github.com/JBorrow/GoGoGadget)):

For Martizzi EOS:

+ f\_Martizzi

+ F\_Martizzi

+ P\_fin -- note this must be simulation units

+ fgas

For fixed NFW:

+ R\_nfw

+ HaloMass

+ c\_nfw
