A New Simulation
CDM+Lambda Model, H0=67, Omega=0.30, Omega_b=0.035, Lambda=0.70, sigma_8=0.90, L=25Mpc/h, Ncell=768^3
This simulation includes galaxy/star formation, energy feedback from supernova explosions, ionization radiation from massive stars and metal recycling due to SNe/galactic winds
In addition, ``metals" are followed as a separate variable, not as an ad hoc add-on
