describes gyrfalcON which is the executable code within the NEMO N-body system.




How to run gyrfalCOn from the NEMO system

The Nemo system is installed at /software/physics/nemo on phcomp.ucsd.edu.

The directory paths are set up by executing: source /software/physics/nemo/nemo_start which will set up all the required environment variables. In the case of trouble check whether the user environment variable NEMO is set to /software/physics/nemo (setenv NEMO /software/physics/nemo).

The command gyrfalcON with appropriate parameter inputs will run the code. For instructions, consult the User Guide and the manual page ( gyrfalcON). The file conversion programs are tabtos and snapprint, and the Aarseth to binary snapshot conversion is discussed in the ntmpv manual page.
