3.1 Fortran directories

The files necessary to compile CO5BOLD are distributed over a few directories in the main directory for. The source files are located as shown in Tab. 3.1.

Table 3.1: List of source directories with path name, abbreviation, and a short description.

Paths	Abb.		Description
for/cons/f90/	CON		constants and units
for/eos/f90/	EOS		equation of state
for/hd/chem/	CHEM		chemical reaction network
for/hd/dust/	DUST		source terms due to dust or molecules
for/hd/hion/f90/	HION		time-dependent hydrogen ionization
for/hd/mhd/	MHD		MHD
for/hd/rhd/	RHD		RHD: main, HD, Bernd's radiation transport
for/hd/rhdb/	RHDB		basic RHD: I/O, box handling, averaging
for/hd/tweak/	TWEAK		various optional tweak modules
for/hd/unitt/	UT		unit-test subroutines and main program

for/time/f90/	TIME		timing
for/uio/f90/	UIO		I/O

The executables (and Makefiles, object files, module information files) are usually located in subdirectories of the source code directories. These subdirectories typically have the name of the machine, architecture, or operating system the executable is compiled for.
