We now explain how
to set the parameters for an individual
simulation in the subdirectory MAIN. There are two type of
preparations for the simulation. Any changes made to the model code in
the files ending in .f, .F, or .h (changing model physics
such as wind
stress, type of diffusion, partial cells, etc.) require that the program
be recompiled with the MAIN/ Makefile. Any changes governing
the model simulation
(timestep, length of run, etc.) can be set in file Runtime_parm.tag
(see below) that is read by the program at time of execution and therefore
do not require compilation.
