#371 closed Enhancement (fixed)

Mixed laplacian and bilaplacian operators

Description

We have added the ability to use mixed laplacian and bilaplacian operators which involves minor changes to the following (attached) files:

DYN/dynldf.F90
LDF/ldfdyn.F90
LDF/ldfdyn_oce.F90

I have run this through the NVTK (at NEMO VN3.1) and tested the changes for the GYRE and ORCA2_LIM standard configurations.
All was fine for both of these with the solver.stat and ocean.output files being exactly the same (save for an expected additional line in the nam_dynldf writeout).

PS. I feel I should add that we have also tested these changes in fairly lengthy hindcasts (for our global (ORCA025) and regional models) as well as using them in our current operational system.

I'm trying to implement your changes in the trunk.
I have some trouble. It seems to me that you forgot some of the files you have modified.
Indeed, as such, I don't see where the ahm0_blp value is used in dynldf_blp.

At least dynldf_blp.F90 has been modified, no ?

Further update from Met Office GMED ticket 371 from
branches/NERC/dev_r5518_GO6_Carb_Fail_from_GO6_9163
to incorporate subsequent chage to the point at which
unrealistic low tempearture warnings are generated.
Original code use -3.0, revised code uses -10.0.
These changes relate purely to warning messages and
do not impact model evolution.
Command:
