Field Documentation

double io_header::BoxSize

box-size of simulation in case periodic boundaries were used Definition at line 615 of file allvars.h. Referenced by write_file().

char io_header::fill[60]

fills to 256 Bytes Definition at line 623 of file allvars.h.

int io_header::flag_cooling

flags whether cooling was included Definition at line 613 of file allvars.h. Referenced by write_file().

int io_header::flag_entropy_instead_u

flags that IC-file contains entropy instead of u Definition at line 622 of file allvars.h. Referenced by init(), and read_header_attributes_in_hdf5().

int io_header::flag_feedback

flags whether feedback was included (obsolete) Definition at line 610 of file allvars.h. Referenced by write_file().

int io_header::flag_metals

flags whether the file contains metallicity values for gas and star particles Definition at line 620 of file allvars.h. Referenced by write_file().

int io_header::flag_sfr

flags whether the simulation was including star formation Definition at line 609 of file allvars.h. Referenced by write_file().

int io_header::flag_stellarage

flags whether the file contains formation times of star particles Definition at line 619 of file allvars.h. Referenced by write_file().

double io_header::HubbleParam

Hubble parameter in units of 100 km/sec/Mpc Definition at line 618 of file allvars.h. Referenced by write_file().

double io_header::mass[6]

mass of particles of each type. If 0, then the masses are explicitly stored in the mass-block of the snapshot file, otherwise they are omitted Definition at line 605 of file allvars.h. Referenced by read_file(), read_header_attributes_in_hdf5(), and write_file().

int io_header::npart[6]

number of particles of each type in this file Definition at line 604 of file allvars.h. Referenced by get_particles_in_block(), read_file(), read_header_attributes_in_hdf5(), and write_file().

unsigned int io_header::npartTotal[6]

total number of particles of each type in this snapshot. This can be different from npart if one is dealing with a multi-file snapshot. Definition at line 611 of file allvars.h. Referenced by read_file(), read_header_attributes_in_hdf5(), and write_file().

unsigned int io_header::npartTotalHighWord[6]

High word of the total number of particles of each type Definition at line 621 of file allvars.h. Referenced by read_file(), read_header_attributes_in_hdf5(), and write_file().

int io_header::num_files

number of files in multi-file snapshot Definition at line 614 of file allvars.h. Referenced by find_files(), read_file(), read_header_attributes_in_hdf5(), and write_file().

double io_header::Omega0

matter density in units of critical density Definition at line 616 of file allvars.h. Referenced by write_file().

double io_header::OmegaLambda

cosmological constant parameter Definition at line 617 of file allvars.h. Referenced by write_file().

double io_header::redshift

redshift of snapshot file Definition at line 608 of file allvars.h. Referenced by write_file().

double io_header::time

time of snapshot file Definition at line 607 of file allvars.h. Referenced by read_file(), and write_file().
