There is no need to define a new mesh, bathymetry, 52 52 initial state or forcing, since the 1D model will use those of the configuration it is a zoom of. 53 The chosen grid point is set in par\_oce.F90module by setting the \jp{jpizoom} and \jp{jpjzoom}53 The chosen grid point is set in \mdl{par\_oce} module by setting the \jp{jpizoom} and \jp{jpjzoom} 54 54 parameters to the indices of the location of the chosen grid point. 55 55 56 The 1D model has some specifies. First, all the horizontal derivatives are assumed to be zero. 57 Therefore a simplified \rou{step} routine is used (\rou{step\_c1d}) in which both lateral tendancy 58 terms and lateral physics are not called, and the vertical velocity is zero (so far, no attempt at 59 introducing a Ekman pumping velocity has been made). 60 Second, the two components of the velocity are moved on a $T$-point. 61 This requires a specific treatment of the Coriolis term (see \rou{dyncor\_c1d}) and of the 62 dynamic time stepping (\rou{dynnxt\_c1d}). 63 All the relevant modules can be found in the NEMOGCM/NEMO/OPA\_SRC/C1D directory of 56 The 1D model has some specifies.
