2MODULE 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.
