Summary

Action AGRIF-01_jchanut_small_jpi_jpj
PI(S) Jérôme Chanut

Digest

Remove restriction on minimum domain size with AGRIF. AGRIF is indeed no more working if the mpi subdomain is so small that all boundary conditions cannot be done within the subdomain.
This happen in fact quite easily for the sponge layer

Abstract

#2199: Take into account masked open boundaries in sponge definition. Output sponge values.

11542jchanut2019-09-13T15:27:41+02:00

#2199: 1) Replace TWO_WAY cpp key by namelist flag ln_agrif_2way. 2) Clean agrif_user module. At this stage, code is reproducible in one way mode down to jpi/jpj=3. Issues for small subdomain sizes (e.g. aprox < 7x7) remain in update (i.e. in 2 way mode). Masking of sponge in unconnected areas has to be implemented. -Cette ligne, et les suivantes ci-dessous, seront ignorées--

#2199, enforce ln_nnogather=.FALSE. if no periodic conditions. Some issues have been encountered in VORTEX test case.

#2199, clean old namelist variables

#2199, remove remaining use of nlcj

11219jchanut2019-07-05T14:07:17+02:00

#2199 1) Define aditionnal arrays to correct the time interpolation of barotropic arrays in corners. Since multiple stages in the time interpolation are necessary, overlapping segments in corners give wrong results otherwise (corrects stage 2 in previous commit).. 2) Added subroutine to correct time extrapolated fluxes at bdy in time splitting routine (updates stage 3 in previous commit). 3) Completly remove non-specified open boundary case. Boundares are now exactly set from parent (no more filtering nor extrapolation for outgoing flows). At this stage, use of nbondi, nbondj variables has been completly removed.

11205jchanut2019-07-02T14:25:46+02:00

#2199 1) Make sponge independent of sub-domain size. Partially masked open boundary segments are not taken into account anymore. To do so, sponge coefficients should be read in a file for realistic applications (then nesting tools need to be modified accordingly). 2) Replace East-West-North-South barotropic data arrays by a global 2d array. Then apply barotropic open boundary conditions thanks to mi0/mi1, mj0/mj1 indexes. 3) Call AGRIF bdy update one more time in dynspg_ts during extrapolation phase. This removes a dozen lines of code in dynspg_ts routine.
