    2929'''   [[BR]]   Nevertheless'''          for both the trunk & this branch, ORCA2_LIM3 blow up atter 138 time step....[[BR]]        NB: to obtain the same results 1 things : revert domhpg.F90 optimization (use of r1_e...) [[BR]]        =========>>>>>>>>>>>>  try to find the origine of the model explosion:[[BR]]        (1) dynvor.F90 reverted to the v3.6_stable  version, i.e. with use of fmask at the proper place, the trunk still explode round the same time-step...  So the problem does not come from dynvor.[[BR]]        (2) iso neutral diffusion switch off (as well as div): it is not the issue the model still blow up (pdt 139)[[BR]]        (3) partial cells switch off (ln_zco=T): it is not the issue the model still blow up (pdt 142)[[BR]]      (4) tra_adv : use 2nd order centered scheme: blow up pdt 134[[BR]]      (5) just set hat as a constant= 2000  (instead of grid depend coeff  nn_aht_ijk = 20) : blow up pdt 134[[BR]]      (6) dynldf off (ln_dynldf_lap=F) & use of UBS (ln_dynadv_vec= F ; ln_dynad_ubs=T): '''      it is working !!!! '''(I stop the run after 3531)[[BR]]The error is thus probably in dynldf_lap_blp.F90. Note that if the code does not blow up it is very noisy at mid latitudes with such a setting... (probably logic with UBS on such a low resolution...).
