! Energy conservation
! Based on the TKE equation
! The M2 and N2 terms at the origin of TKE production are
! concerted into heating in the d_t_ec term
! Option 1 is the standard
!        101 is for M2 term only
!        101 for N2 term only
!         -1 is a previours treatment for kinetic energy only
