Fortran 77 package NET version 3.00

Compiling and linking programs of package NET

• Copy all files (or at least files ram.inc, sep.for, sep.inc, length.for and forms.for) of package FORMS into your working directory. All the files including subdirectories may also be extracted using pkunzip -d forms.zip or tar -xvf forms.tar
  On a computer with a very small memory (less than 16 MB), you may need to decrease array dimension MRAM in the include file ram.inc.
  It is also recommended to compile and link all programs of package FORMS according to the description in forms.htm.
• Copy all files (or at least all *.for and *.inc files) of package NET into your working directory. All the files including subdirectories may also be extracted using pkunzip -d net.zip or tar -xvf net.tar
• Now you may compile and link following program of package NET:
  • net.for
  All necessary subroutine files and include files are included by the Fortran 90 INCLUDE command. Fortran 77 subroutine files are included at the end of file net.for.
  Under Unix, you may perform the above task by editing script f designed to compile and link a single file and then entering command f net. The script must be made executable.
  Under MS-DOS, you may perform the above task by editing batch file f.bat designed to compile and link a single file and then entering command f net.

• In addition to the above steps, copy all files of subdirectory fv of package NET into your working directory.
• Now you may compile and link following program of package NET:
  • netind.for
  All necessary subroutine files and include files are included by the Fortran 90 INCLUDE command. Fortran 77 subroutine files are included at the end of file netind.for.

Running programs of package NET

Data from standard input *:

Main input data of each program are read from the standard input, and mostly consist of a single line containing filenames and at most few numerical parameters.

Description of input data for the NET program

Regular network ray tracing.

Description of input data for the NETIND program

Network ray tracing inside Fresnel volumes.
