Description
Development branch related to CNRS-9 and NOC-3 actions of 2015 work plan :
simplify and improve the lateral diffusion and dissipation in NEMO/OPA
generalization of the use of surface scale factors (e1e2 at T, U, V, F points)
NB: This development consists in merging the current trunk with the last year work on that subject (see ticket #1260, and the associated branch 2014/dev_CNRS0_NOC1_LDF and wiki page 1260_CNRS0_NOC1_LDF.
Simplification:
(1) define bi-laplacian diffusive operator on dynamics and tracers are re-entrant laplacian
(2) change the way the eddy diffusivity and viscosity are specified and controlled by the user.
(3) generalize of the use of surface scale factors
(4) add a optional read of surface scale factors in coordinate file in case of reduction of the scale factors in some straits.
Improvements:
(1) introduce Beckers et al. (2000) compact stencil in the cross-isoneutral direction in triads formalism ;
(2) introduce in both iso-neutral operator the Method of Stabilizing Correction (Lemarié et al. (2012) ;
(3) implement bilaplacian iso-neutral operator (Lemarié et al. (2012)
