cpl_mod.F90 @ 2529

Last change on this file since 2529 was 2429, checked in by Laurent Fairhead, 9 years ago
Correction on the calculation of the surface of the grid at the poles (problem was introduced in r2222). Due to the different distribution of OMP tasks in the dynamics and the physics, had to introduce 2 new logical variables, is_pole_north_phy and is_pole_south_phy, and so decided to rename the old is_north_pole/is_south_pole to is_north_pole_dyn/is_south_pole_dyn to stay coherent and, hopefully, clear things up a bit.

2	MODULE cpl_mod
3	!
4	! This module excahanges and transforms all fields that should be recieved or sent to
5	! coupler. The transformation of the fields are done from the grid 1D-array in phylmd
6	! to the regular 2D grid accepted by the coupler. Cumulation of the fields for each
7	! timestep is done in here.
8	!
9	! Each type of surface that recevie fields from the coupler have a subroutine named
10	! cpl_receive_XXX_fields and each surface that have fields to be sent to the coupler
11	! have a subroutine named cpl_send_XXX_fields.
