Hello Tim and Fab,
You are right about the latest ARTEMIS manual, there is none. Regarding your issue, first of all I suggest you read the paper "ARTEMIS developments at HR Wallingford" from the TUC2018 Conference Proceedings. It is the only documentation of the TOMAWAC-ARTEMIS chaining.
I believe things have moved on a bit since then and developments are undocumented. I quickly mention the keywords you need to define to setup chaining (from my notes, in hope they are not outdated):
TOMAWAC
PUNCTUAL RESULTS FILE
FILE WITH COORDINATES OF SPECTRA TO WRITE (a dat file with sample coordinates along the ARTEMIS boundary)
2D RESULTS FILE (of course)
ARTEMIS
TOMAWAC OUTER SPECTRAL FILE: .SPE <--PUNCTUAL RESULTS FILE
TOMAWAC OUTER RESULT FILE : .SLF <-- 2D RESULTS FILE
TOMAWAC LIQUID BOUNDARY FILE: .LQD <--Created with 'convert_to_bnd.py' python script from 'pretel'.
INSTANT FOR READING TOMAWAC SPECTRUM: [time]
NESTING WITHIN TOMAWAC OUTER MODEL: 2
COORDINATES OF THE REFERENCE F SPECTRUM: [x];[y]
The .LQD file can be created as follows:
convert_to_bnd.py ARTEcliFile ARTEgeoFile TOMslfFile ARTEbndFile
Best Regards,
Costas
