    2929logical flags added in namlist namtrd which now controls what is done with the trends. [[BR]] All the types of treatment of a given trend are available at the same time. The memory requirement will only increase due to the time averaged arrays defined in IOM.

    5959suppress the call to trd_mod in the jpdyn_trd_dat case (computation of beta.V) add add the calculation of beta.V term in 'trdvor' in jpvor_pvo case. And obviously suppress jpdyn_trd_dat from trdmod_oce [[BR]] Also suppress the jpdyn_trd_had case  horizontal advection for the dynamics is 'keg' + 'vor'  ; in case of flux form,  'had' is put in 'keg' and the metric terms is put in 'vor' [[BR]] there is now only 10 trends on the dynamics instead of 12[[BR]] [[BR]]

    6767add in trd_twr routine the computation of the vertical diffusive trend on T & S in case of iso-neutral diffusion (ln_traldf_iso=T). These trends ("ttrd_zdfp", "strd_zdfp")  name zdfp for "PURE" vertical diffusion trends are output so that by difference with "zdf" trends we can access to the vertical contribution of the iso-neutral operator [[BR]] [[BR]]

    79791- suppress trdicp_oce module (put required variables in trdmod_oce parameters)[[BR]] 2- use the jptra_trd_...  instead of jpicp_...  3- move trd_budget subroutine from trdmod to trdicp.F90. Suppress trd_icp routine (i.e. trd_2d, trd_3d) as the work is now simply done in trd_budget.[[BR]] 4- rescan all dyn/tra trend indices. add jptra_trd_zdfp for "PURE Kz dissusive trend when ln_traldf_iso=T (see also changes in tranxt where a call to trd_tra is done just before the swap, so that PURE Kz trends can be diagnosed in tra_trd. See also xml file).  5- jptra_trd_nsr and jptra_trd_cdt are 3D trends as their incorporate both surface forcing AND runoff, the later being possibly spread in depth ('''==>>> probably to be changed''')[[BR]] 6- suppress the key_trddyn key trdtra  from trdicp[[BR]]

    129129  problems to be solved: vvl case for tracer sad trends ; flux form case for had (keg) and zad momentum trends[[BR]] 
     
    219219   * Same for alpha and beta 
    220220 * eos_alpha_beta added, which provides alpha and beta 
    221  * pen_ddt_dds added to provide partial derivatives of PE with respect to T and S, needed in PE diagnostic (trdpen). 
     221 * pen_ddt_dds added to provide partial derivatives of PE with respect to T and S + PE itself, needed in PE diagnostic (trdpen). 
    222222 * TODO: add global arrays for alpha and beta, computed at the same time than bn2? Indeed, they are used in several places, and are needed to compute bn2 in any case... 
    223223 * BUG: I don't understand why, but the linear case 1 is very slow, contrary to the others. Could it be coming from eos_alpbet? 
    224224 
     225In trdtra.F90 
     226 
     227 * Add 'trdt(:,:,:) = ptrd(:,:,:) * tmask(:,:,:)' in CASE jptra_bbc in trd_tra (l. 103) 
     228 
    225229In trdpen.F90 
    226230 
    227231 * replace petrd_ldf by petrd_zdf in l. 102 
    228232 * renamed petrd_for as petrd_nsr for consistency with trd_oce (l. 107) 
     233 * remove lines on petrd_sad in CASE jptra_atf in trd_pen: petrd_sad cannot be called 2 times. Furthermore, contribution of asselin filter on ssh must be diagnosed in ssh_nxt, not in tra_nxt!! 
     234 * Remove '( nn_eos == 0 .OR. nn_eos == 3 ) .AND. ' in the condition to call pen_ddt_dds in trd_pen (l. 79). These two coefficients are updates at each timestep whatever the eos (very quick anyway for the linear case!) 
     235 * Add 'CALL iom_put( "potential_energy", zpe )' in trd_pen, just after the call to pen_ddt_dds. 
     236 * Replace ptrdx by ptrdy and remove multiplication by fsde3w to compute pe trends in trd_pen (l. 88-89) 
     237 
     238Bug during compilation: 
     239 
     240 * make: Circular dynhpg.o <- trddyn.o dependency dropped[[BR]]patched by compiling a first time with the line 'USE trddyn' commented in dynhpg.F90, then recompiling with 'USE trddyn' decommented.
