For a documentation about the code, see jorek.eu/wiki

to build jorek2:

- edit the Makefile.inc file to match your environment
  (some examples are available in the directory configs)
  
  choose a model : model199 (reduced MHD, no v_parallel)
                   model300 (reduced MHD, with V_parallel)

- edit the model dependent mod_parameters.f90 file to define
  n_tor    : the number of toroidal harmnonics (sin+cos) 
  n_plane  : the number of toroidal planes (for FFT)
  n_period : the periodicity of the torus
  
- make all (in top directory)

to execute jorek2:

mpirun -np n_mpi jorek2_model199 < namelist/model199/intear

this is a simple testcase (example output is available in test_output)

the number of mpi's should be a multiple of the number of harmonics ((n_tor-1)/2+1)


Topic: Timing

We use the "r3_info" package from R. Richter, SGI, Oct 2006 (trunk/timing) to compute elapsed time in JOREK.
Ask G. Latu (guillaume.latu@cea.fr) for more details.
To use it, we need
 - Fortran preprocessing options: -cpp -DUSE_R3_INFO_MPI -DUSE_R3_INFO (see trunk/configs/config.hpcff)
 - define a MPICC compiler and preprocessing options: -DUSE_R3_INFO_MPI -DUSE_R3_INFO (see trunk/configs/config.hpcff)
 - need #include "r3_info.h" statement (warning: C syntax with #) in Fortran file (see trunk/jorek2_main.f90 for example)
