The associated branch is ​2015/dev_r5224_CNRS_OPA_Hollingsworth

A namelist parameter has been added (nn_dynkeg in the namdyn_adv namlist). Setting it to zero you get the old scheme (i.e. a 2nd order scheme that conserve energy) ; setting nn_dynkeg to 1 you get the Arakawa 2001 scheme that prevent the development of the instability reported by Hollingsworth et al (1983). The later scheme does not formally conserve the KE.

The default value of nn_dynkeg is set to 0 in namlist_ref. No changes in namelist_cfg of any configurations, so none of them is using the new scheme.

In the code itself only 2 module has been changed dynadv.F90 and dynkeg.F90

Changes has been committed ( see 5254 )
