Each HDF5 dataset contains triplets of fields: -7_8mdm001R_dt_015 contains "Density", "Dark_Matter_Density" and "Temperature" (a 512^3 grid for each); -7_8mdm001R_v_015 contains "x-velocity", "y-velocity" and "z-velocity" gas velocity fields (a 512^3 grid for each); -7_8mdm001R_b_015 contains "Bx", "By" and "Bz" - the components of the magnetic field (a 512^3 grid for each). All values must be multiplied by the following conversion factors in order to get them in CGS units, given in the corresponding conv2 files, in which the 3rd entry is the redshift (z), the 4th (convd) entry gives the conversion to have Density and Dark_Matter_Density in g/cm^3; while the 5th entry (convv) gives the conversion for velocity components in cm/s; -convb=sqrt(convd4pi)convv*(1+z)^2. to have the magnetic field components in Gauss. The comoving cell resolution is 7.9 kpc/cell. The model started from a uniform seed magnetic field of 0.1nG (comoving). Cosmological AMR simulations performed with the ENZO code, using the Dedner MHD method.
