5! Energy conservation
6! Based on the TKE equation
7! The M2 and N2 terms at the origin of TKE production are
8! concerted into heating in the d_t_ec term
9! Option 1 is the standard
10!        101 is for M2 term only
11!        101 for N2 term only
12!         -1 is a previours treatment for kinetic energy only
