181	SWAN coupling mpi_finalize	jcwarner	arango	"for the '''SWAN''' coupling, the call '''mpi_finalize''' is now located at the bottom of '''Master/mct_coupler.h'''

Here is the problem:

It is not clear which model will get there first.  Typically this will be '''ROMS'''. However, '''SWAN''' needs time to collect the contents of the individual output files and conglomerate them into single output files (don't ask me why '''SWAN''' does this, it is just the way it is). But if '''ROMS''' goes thru it's finalize step, then calls '''mpi_finalize''', well that is bad news for the '''SWAN''' because it may not have finished pulling together the output.

Suggested Solution:

Place an '''mpi_barrier''' in '''mct_coupler.h''' before the call to '''mpi_finalize''' so that all processors from all models need to check in before finalize occurs.
