Species Information not transmitted across interfaces

[DoctorRobertT]

Describe the bug
When using species transport in a problem using the fluid-fluid interface there is no information on species being transmitted across the interface. In addition if you use the MARKER_ANALYZE in the cfg file the code bombs on startup as follows:

Error in "virtual void CMultizoneOutput::SetMultizoneHistoryOutputFields( const COutput* const*, const CConfig* const*)":

Per Surface output group unknown: SPECIES_COEFF_SURF
------------------------------ Error Exit ------------------------------

Hi,

OK, there were actually 2 problems here. One is that the species mass fractions were not transported across the zone interface. The other is that for MARKER_ANALYZE, we did not add species information, but later in the code we assumed that it was present.

Both are now fixed in the feature branch, but it will be a while before it ends up in the master version. In the mean time, you could clone the SU2 git repository and then do a git checkout feature_species_multizone and compile the fixed branch yourself.
Thanks for spotting the problem!

@DoctorRobertT this is now merged in develop. Please check out the testcase in Testcases/species_transport/multizone and let us know of any other missing functionality. Thanks!
