guide_p_mod.F90 @ 5429

Last change on this file since 5429 was 2134, checked in by lguez, 10 years ago

In nudging procedures, replaced explicit Euler integration of nudged
fields by exact integration. This does not change anything if
guide_add is true, but it changes the value of alpha if guide_add is
false. We could have taken into account the variation of the nudging
field during a nudging time step. This would be a small correction. We
choose not to take it into account for the time being. Also, we add a
restriction on zonal nudging: we allow it only for a grid which is
regular in longitude. It does not seem to make sense otherwise and the
exact integration would take more programming for an irregular grid.

In the sequential version, copying the parallel versions, set
iguide_int to 1 when the input value is 0.
