OW COUPNG : WW3 stable release and CROCO for the moment not really compatible
In WW3 v 6.07.1, the variable THM is not exchanged, while it is what we need for CROCO.
- This exchange can be added "by hand" in WW3
- or we could point to a different version to download ? (but then we need to deal with compilation in the tools, because WW3 compilation procedure has changed after this version).
