Adding new slice outputs for a special module

[Hongzhe Zhou]

Hi All,

I'm creating a new special module with a few new variables f(:,:,:,inew1), f(:,:,:,inew2) etc.

I'm wondering how to add new output of slices (i.e. video files) of these new variables (say p%inew1) and their combinations (say p%inew1**2+p%inew2**2)? I tried to look into other modules to find an example but got confused. If someone could clarify the calling tree it would be great!

Best regards,

Hongzhe

Hi Hongzhe,

best you look into hydro.f90. For slices, which contain simply f-array variables, 

you do something like

        case ('uu'); call assign_slices_vec(slices,f,iuu)

in get_slices_hydro. For slices, which contain derived quantities like your p%inew1**2+p%inew2**2

you have to declare slice buffers as for divu in hydro (divu_xy etc.), you have to allocate them like

      if (ivid_divu/=0) call alloc_slice_buffers(divu_xy,divu_xz,divu_yz,divu_xy2,divu_xy3,divu_xy4,divu_xz2,divu_r)

to fill them in calc_diagnostics_special like

        if (ivid_divu/=0) call store_slices(p%divu,divu_xy,divu_xz,divu_yz,divu_xy2,divu_xy3,divu_xy4,divu_xz2,divu_r)

and finally to store them in get_slices_special like 

          call assign_slices_scal(slices,divu_xy,divu_xz,divu_yz,divu_xy2,divu_xy3,divu_xy4,divu_xz2,divu_r)

.

Best,

Matthias
