TYCHO: Getting Started
Running tycho6.9
- TYCHO has on-line graphics using PGPLOT, which is used by subroutines
pgplot.f, cvplt.f, hrplt.f, and dbplt. After unpacking the tycho-6.9 tarfile,
cd tycho-6.9
src/check_config
in the
tycho-6.9 directory.
This shell script will check to see if your machine has the software needed.
Example
- See the PGPLOT setup page for
detailed instructions for testing your machine for an already installed PGPLOT,
and for obtaining and installing PGPLOT if necessary.
- After testing PGPLOT, go to the subdirectory tycho-6.9/src
cd src
make all
to start compilation of the suite of TYCHO programs.
- If successful, go back to the root TYCHO directory
cd ..
tycho6
and tycho should start, taking parameters from the file params.d,
reading in an initial model from the file imodel, and getting data
for equation of state, opacities, and reaction rates as needed.
- Tycho should bring up 3 PGPLOT windows, evolve the model
(a 6 solar mass star just born on the Hayashi track) for 5 time
steps.
If all went well, you will have run tycho6 briefly.
To continue the run:
Edit the file /tycho-6.9/params.d
to change the number of time steps line to
' Number of timesteps for this run...........' 'll' 1000
for a long run. This should take the model well beyond the main sequence.
Understanding the on-line graphics windows.
TYCHO-6.9 uses both on-line graphics and off-line graphics. The on-line
graphics are shown in three PGPLOT xwindows described below.
Several auxillary programs
provide windows or postscript files for analysis and hardcopy
(see /tycho-6.9/README).
A longer run
These 700 steps took 36 minutes on a desktop with a 2.4GHz Pentium 4 cpu,
and 18 minutes on an AMD Athlon 64 3700+ laptop.
