Hi Jean-Michel,

I am sorry, I only checked the lab_sea adjoint on my machine and there I did not observe any changes.What I did is moved some code (computation of DWATN) into a subroutine, that can be called by all three solvers. I thought is was a good idea, maybe not? Would you expect changes in truncation? I wouldn't, but maybe I am wrong.
