Hi, i am trying to simulate a TELEMAC-3D case coupling with GAIA, which contains 3 sources and 1 tracer. In the t3d.cas, following the error message, i have given 6 VALUEs OF THE TRACERS AT THE SOURCES. However, it still didn't work. Has anyone else had this problem and can help me out?

The attachments is the cas for telemac-3d and the error.

Also, I'd like to inquire about the keyword VALUE OF THE TRACERS AT THE SOURCES, which is still required even though I've created a file of sources and tracers over time for import. Will this keyword definition be replaced by my source file when my case is running normally?

Hi
The computation stops in lecdon_telemac3d.F

      IF(NTRAC.GT.0.AND.NPTSCE.GT.0) THEN
        DIMTOT=DIMEN(2,84)
        IF(INCLUS(COUPLING,'GAIA').AND.IND_SED.GT.0) THEN
          DIMTOT=DIMEN(2,84)+NSEDSCE
        ENDIF
        IF(DIMTOT.NE.NTRAC*NPTSCE) THEN
          WRITE(LU,*) 'WRONG NUMBER OF'
          WRITE(LU,*) 'VALUE OF THE TRACERS AT THE SOURCES'
          WRITE(LU,*) DIMEN(2,84),' GIVEN'
          WRITE(LU,*) NTRAC*NPTSCE,' EXPECTED'
          CALL PLANTE(1)
          STOP
        ENDIF

In the Telemac steering file, you should have 3 values (1 tracer and 3 sources) in VALUE OF THE TRACERS AT THE SOURCES... (DIMEN(2,84))
In GAIA, the number of values of SUSPENDED SEDIMENTS CONCENTRATION VALUES AT THE SOURCES gives the value of NSEDSCE which should also be 3 if you have only 1 sediment.
As you give 6 values in telemac, the comparison give DIMTOT = 9 and NTRAC*NPTSCE = 6...
I think if you give only 3 values in telemac steering file (as it should be), this will be OK
As the message print DIMEN(2,84) and not DIMTOT, this is confusing...
THis should be something to correct for the next version...

Hope this helps
