Description

Workplan action

In addition to the standard anti-symmetric operator (div(grad)-rot(rot)) we add the Griffies & Hallberg (MWR 2000) symmetric operator as an option.

The choice is controled by a new namdyn_ldf parameter :

   nn_dynldf_typ = 0           !  =0 div-rot (default)   ;   =1 symmetric

NB: The default value is the standard operator and the viscous coefficients are the same for both operators.

This development is included in KERNEL-06 action.
