guide_loc_mod.F90 @ 2495

Last change on this file since 2495 was 2263, checked in by lguez, 10 years ago

In the sequential version, ini_getparam and fin_getparam were not
called so guide_init created a file "fort.99". Added call to
ini_getparam and fin_getparam in guide_init. The created file is now
"nudging_parameters_out.txt".

In the parallel version, ini_getparam was called from gcm, with the
argument "out.def". So "out.def" was created even without nudging, it
remained empty. Moved the call to ini_getparam from gcm to
guide_init. Also changed the name of the created file to
"nudging_parameters_out.txt", as in the sequential version. "out.def"
was too vague and confusing a name.
