Test+Data+Access

=**Access to data and software for creating test problem initial conditions**= Test problem pages: Overview, Data Access, Utilities, Work Area Setup, Path Setup, Grid Data, SPH Data

You need a CADAC account to access the data and the software.

Initial Data Files
To access the initial data files from UNIX, login to **dsdirect.sdsc.edu**, and do

cd /gpfs-wan/projects/cadac/srbVault/aake.cadac/home/aake.cadac/KITPcompare07/ ls -l

The original, 1000^3 snap shots from which the initial conditions are derived, are in the directory /gpfs-wan/projects/cadac/srbVault/aake.cadac/home/aake.cadac/STAGGER/cm1000b, with a soft link "cm1000b" to the KITPcompare07 directory.

To access the files with [|SRB commands], do

cd Sinit Scd /home/aake.cadac/KITPcompare07/ Sls -l

Test Problem Utilities
A number of test problem utilities are available, for creating specific initial conditions for your HD or MHD grid code, and for creating SPH data with any required resolution. Binaries have been placed in /gpfs-wan/projects/cadac/software/contrib/aake/codes/KITPcompare07/bin, so add this to your UNIX path.

Here is a simple example on how to set up a subdirectory under your **/gpfs/$user/** directory, for generating user-specific initial conditions:

mkdir /gpfs/$user/KITPcompare07 cd /gpfs/$user/KITPcompare07 ln -s /gpfs-wan/projects/cadac/srbVault/aake.cadac/home/aake.cadac/STAGGER/cm1000b cm1000b ln -s /gpfs-wan/projects/cadac/srbVault/aake.cadac/home/aake.cadac/KITPcompare07 data g2g.x data/hd_256.g2g

This creates a raw binary file **hd_256.dat**, and a small text file **hd_256.dim** describing the data. The binary file contains the density and the three velocity components. To access the data from you own code you probably need to convert the data to a different format. Other aspects of the data, such as numerical resolution and centering of the velocities may be controlled with parameters in the input file. To change these, copy the file to your own directory, edit it, and run the program (g2g.x) again:

cp data/hd_256.g2g test.g2g vim test.g2g g2g.,x test.g2g =**Access to data and software for creating test problem initial conditions**=
