hi,
I try to modify the kpp mixing scheme through adding a coefficient to AKT and AKv, I modified some fortran program to read the bv coefficient as a forcing file,as:
nc = netcdf('E:\bvdata\bv_hrho1.nc', 'noclobber');
if isempty(nc), return, end
%% Global attributes:
%% (none)
%% Dimensions:
nc('xi_rho') = 461;
nc('eta_rho') = 237;
nc('s_rho') = 16;
nc('bv_time') = 12;
%% Variables and attributes:
nc{'s_rho'} = ncdouble('s_rho'); %% 16 elements.
nc{'s_rho'}.long_name = ncchar(''S-coordinate at RHO-points'');
nc{'s_rho'}.units = ncchar(''nondimensional'');
nc{'s_rho'}.valid_min = ncdouble(-1);
nc{'s_rho'}.valid_max = ncdouble(0);
nc{'bv_time'} = ncdouble('bv_time'); %% 12 elements.
nc{'bv_time'}.long_name = ncchar(''time since initialization'');
nc{'bv_time'}.units = ncchar(''days'');
nc{'bv_time'}.cycle_length = ncdouble(360);
nc{'lon_rho'} = ncdouble('eta_rho', 'xi_rho'); %% 109257 elements.
nc{'lon_rho'}.long_name = ncchar(''longitude of RHO-points'');
nc{'lon_rho'}.units = ncchar(''degree_east'');
nc{'lat_rho'} = ncdouble('eta_rho', 'xi_rho'); %% 109257 elements.
nc{'lat_rho'}.long_name = ncchar(''latitude of RHO-points'');
nc{'lat_rho'}.units = ncchar(''degree_north'');
nc{'BV'} = ncdouble('bv_time', 's_rho', 'eta_rho', 'xi_rho'); %% 20977344 elements.
nc{'BV'}.long_name = ncchar(''wave mixing'');
nc{'BV'}.units = ncchar(''m second-2'');
nc{'BV'}.time = ncchar(''bv_time'');
endef(nc)
close(nc)
and to be sure add this coefficient,I modify LMD_vmix.f and put out some number,as:
# ifdef WAVE_MIXING
if(i == 300..and.j==50)then
write(*,*)'k1',k,'tv1',Akv(i,j,k),Akt(i,j,k,1)
write(*,*),'bv1',bv(i,j,k)
endif
AKv(i,j,k)=AKv(i,j,k)+bv(i,j,k)*1.0_r8
AKt(i,j,k,itemp)=AKt(i,j,k,itemp)+bv(i,j,k)*1.0_r8
if(i == 300..and.j==50)then
write(*,*)'k2',k,'tv2',Akv(i,j,k),Akt(i,j,k,1)
write(*,*),'bv1',bv(i,j,k)
endif
# endif
model is running,and I get log file show that:

Can be seen from the above，bv coefficient have been added to AKT and AKV;
but when i check the result, the temp,AKT,akv are no change，In a certain point, for example:
model result which no change: akt(300,50，：，1)；
