Each HDF5 dataset contains triplets of fields:
-6_8mdm001R_dt_012 contains "Density", "Dark_Matter_Density" and "Temperature" (a 640^3 grid for each);
-6_8mdm001R_v_012 contains "x-velocity", "y-velocity" and "z-velocity" gas velocity fields (a 640^3 grid for each);
-6_8mdm001R_b_012 contains "Bx", "By" and "Bz" - the components of the magnetic field (a 640^3 grid for each).
All values must be multiplied by the following conversion factors in order to get them in CGS units:
-convd=4.342187e-30 to have Density and Dark_Matter_Density in g/cm^3;
-convt=1 for the temperature in K;
-convv=6.4770872e+09 to have the velocity components in cm/s;
-convb=sqrt(convd4pi)convv(1+z)^2. to have the magnetic field components in Gauss.
The comoving celle resolution is 15.8 kpc/cell and the redshift is z=0.2.
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.
