summary:

Gryschka:

- Coupling with different resolution and different numbers of PEs in
ocean and atmosphere is available
- Exchange of u and v from ocean surface to atmosphere surface
- Mirror boundary condition for u and v at the bottom are replaced
by dirichlet boundary conditions
- Inflow turbulence is now defined by flucuations around spanwise mean
- Bugfixes for cyclic_fill and constant_volume_flow

Suehring:

- New advection added ( Wicker and Skamarock 5th order ), therefore:
- New module advec_ws.f90
- Modified exchange of ghost boundaries.
- Modified evaluation of turbulent fluxes
- New index bounds nxlg, nxrg, nysg, nyng

advec_ws.f90

Advection scheme for scalars and momentum using the flux formulation of

Wicker and Skamarock 5th order.

Additionally the module contains of a routine using for initialisation and

steering of the statical evaluation. The computation of turbulent fluxes takes

place inside the advection routines.

In case of vector architectures Dirichlet and Radiation boundary conditions are

outstanding and not available. Furthermore simulations within topography are

not possible so far. A further routine local_diss_ij is available and is used

if a control of dissipative fluxes is desired.

check_parameters.f90

Exchange of parameters between ocean and atmosphere via PE0

Check for illegal combination of ws-scheme and timestep scheme.

Check for topography and ws-scheme.

Check for not cyclic boundary conditions in combination with ws-scheme and

loop_optimization = 'vector'.

Check for call_psolver_at_all_substeps and ws-scheme for momentum_advec.

Different processor/grid topology in atmosphere and ocean is now allowed!

Bugfixes in checking for conserve_volume_flow_mode.

exchange_horiz.f90

Dynamic exchange of ghost points with nbgp_local to ensure that no useless

ghost points exchanged in case of multigrid. type_yz(0) and type_xz(0) used for

normal grid, the remaining types used for the several grid levels.

Exchange is done via MPI-Vectors with a dynamic value of ghost points which

depend on the advection scheme. Exchange of left and right PEs is 10% faster

with MPI-Vectors than without.

flow_statistics.f90

When advection is computed with ws-scheme, turbulent fluxes are already

computed in the respective advection routines and buffered in arrays

sums_xxxx_ws_l(). This is due to a consistent treatment of statistics

with the numerics and to avoid unphysical kinks near the surface. So some if-

requests has to be done to dicern between fluxes from ws-scheme other advection

schemes. Furthermore the computation of z_i is only done if the heat flux

exceeds a minimum value. This affects only simulations of a neutral boundary

layer and is due to reasons of computations in the advection scheme.

inflow_turbulence.f90

Using nbgp recycling planes for a better resolution of the turbulent flow near

the inflow.

init_grid.f90

Definition of new array bounds nxlg, nxrg, nysg, nyng on each PE.

Furthermore the allocation of arrays and steering of loops is done with these

parameters. Call of exchange_horiz are modified.

In case of dirichlet bounday condition at the bottom zu(0)=0.0

dzu_mg has to be set explicitly for a equally spaced grid near bottom.

ddzu_pres added to use a equally spaced grid near bottom.

init_pegrid.f90

Moved determination of target_id's from init_coupling

Determination of parameters needed for coupling (coupling_topology, ngp_a, ngp_o)

with different grid/processor-topology in ocean and atmosphere

Adaption of ngp_xy, ngp_y to a dynamic number of ghost points.

The maximum_grid_level changed from 1 to 0. 0 is the normal grid, 1 to

maximum_grid_level the grids for multigrid, in which 0 and 1 are normal grids.

This distinction is due to reasons of data exchange and performance for the

normal grid and grids in poismg.

The definition of MPI-Vectors adapted to a dynamic numer of ghost points.

New MPI-Vectors for data exchange between left and right boundaries added.

This is due to reasons of performance (10% faster).

ATTENTION: nnz_x undefined problem still has to be solved!!!!!!!!
