Files
------------------------------------------------------------------------

From the tarred/zipped files you should get the directory structure:

  \track           -main directory plus configure and make files
    \bin           -binaries
    \dat           -data
    \doc           -documentation
    \lib           -libraries
    \results       -results
    \src           -source code

There are two versions of the test code -- one that links to AJAX and
one that links to XPLASMA -- and each of these has test cases.
Each test case generates 3 output files:

1d\_s\_track.dat   -1D output along path for IDL postprocessing
sum\_track.dat     -1D output along path for viewing with editor
msg\_track.dat     -Error, warning and other messages

Sample output files for each test case have a case name appended and
either 4 or 8 designating the precision set in SPEC_KIND.MOD, which
can be editted to change the precision.

TRACK/AJAX can be run in either 'single' or 'double' precision,
and TRACK/XPLASMA can only be run in 'double' precision.

The precision parameters are therefore set to 'double' in the
distribution to cover both.


TRACK/AJAX and TRACK/XPLASMA on a UNIX system
------------------------------------------------------------------------

On a UNIX system you can configure the makefile with the command:

./configure --with-library-path=[library source]

where [library source] is needed for the TRACK/XPLASMA
option and includes the xplasma and pspline libraries
available through the NTCC library (at PPPL these are located at
/usr/ntcc/lib).
Also, the lapack and blas libraries are needed.

For SUN Solaris systems the f77compat library needs to be specified, if
the library is not in the standard lib directory (/usr/lib,
/usr/local/lib, /lib, and etc).
For example, for the PPPL Orion workstation it takes the form:

./configure --with-library-path=/usr/ntcc/lib/ \
--with-f77compat-library=/afs/pppl.gov/sun4x_56/opt/SUNWspro/SC5.0/lib

The f77compat library is not required for non-SUN systems and configure
will look like:

./configure --with-library-path=/usr/ntcc/lib/

Then 'make' can be run with the following options:

make ajax       to make TRACK/AJAX
make xplasma    to make TRACK/XPLASMA
make atesttok   to run TRACK/AJAX on generic tokamak case
make atestnstx  to run TRACK/AJAX on NSTX tokamak case
make atestncsx  to run TRACK/AJAX on NCSX stellarator case
make xtestnstx  to run TRACK/XPLASMA on NSTX tokamak case
make clean      to remove *.o, *.mod files
make realclean  to remove *.o, *.mod plus library and binary files

The output from each test case is compared with the reference output
and the results are stored in the \results directory


TRACK and AJAX Sources and Test Cases
------------------------------------------------------------------------

Source routines:

TRACK_AJAX_DR.F90 Driver for TRACK coupled to AJAX
SPEC_KIND.F90     Precision specification module
TRACK_MOD.F90     TRACK module
WRITE_MOD.F90     Formatted output module
SETUP_AJAX.F90    AJAX setup routine
AJAX_MOD.F90      AJAX module
LINEAR1_MOD.F90   1D linear interpolation module
SPLINE1_MOD.F90   1D spline interpolation module

Simple tokamak test case.
-------------------------
Copy nml\_track\_tok.dat to nml\_track.dat and execute.

NSTX (low A tokamak) test case.
-------------------------------
Copy nml\_track\_nstx.dat to \com nml\_track.dat and execute.
This case gets VMEC inverse coordinate expansion coefficients from
in\_nstx\_8.dat.

NCSX (stellarator) test case.
-----------------------------
Copy nml\_track\_ncsx.dat to nml\_track.dat and execute.
This case gets VMEC inverse coordinate expansion coefficients from
\com in\_ncsx\_8.dat.


TRACK and XPLASMA Sources and Test Case
------------------------------------------------------------------------

Source routines:

TRACK_XPLASMA_DR.F90 Driver for TRACK coupled to AJAX
SPEC_KIND.F90        Precision specification module
TRACK_MOD.F90        TRACK module
WRITE_MOD.F90        Formatted output module
SETUP_XPLASMA.F90    XPLASMA setup routine
AJAX_XPLASMA_MOD.F90 Conversion of AJAX calls to XPLASMA calls

In addition, you will need the libraries discussed above.

NSTX (low A tokamak) test case.
-------------------------------
Copy nml\_trackx\_nstx.dat to nml\_track.dat and execute.
This case gets inverse coordinate expansion coefficients from
11114p06.treq\_data.


Documentation
------------------------------------------------------------------------
There is a 28-page document (/track/doc/track.pdf) describing the TRACK
module in detail.
