open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all ;
I'm a user of Telemac 2D, french version. I would like to know the equivalence key word CONCENTRATION PER CLASS AT BOUNDARIES (version English) in french version (used in steering file).
In addition, if I want imposed the value of mass concentration (and bed load transport) changing with time at frontiers, what does the file and key word I have to use? (in steering file and QH.qsl file or other file else?). Thank you in advance for your help.
Best regards

Hello Thong,

You can see all the equivalences in the dictionary of the Sisyphe program, which is :

....../V6P2/sisyphe/sisyphe_v6p2/lib/sisyphev6p2.dico

In your case it is :

CONCENTRATIONS PAR CLASSE AUX FRONTIERES

With best regards,

Salut J. M. Hervouet ;

Hello,

I am, too, facing an issue regarding an imposed concentration and solid discharges at boundaries.
I would like to impose a concentration at one of the liquid boundary. First I tried to use the key word "CONCENTRATIONS PAR CLASSES AUX FRONTIERES" and the graphic printout variable CS1. No concentration can be seen in the domain.
Then I tried to implement a fortran subroutine 'conlit.f',changing features in the right loop =>> CBOR%ADR(1)%P%R(K)=0.001 for instance
But it does not work either.

Regarding the imposed solid discharge at the boundary, I used the same subroutine and added QBOR%ADR(1)%P%R(K)=0.001 where K is the boundary points
It works only for the piece of mesh at the very near of the boundary line. Solid discharge does not spread into the domain.

I managed to modify the fourth column in the BOUNDARY CONDITION FILE, which is linked to Q2BOR:
4 5 5 1E-4 0 0 0 4 0 0 0
LIHBOR LIQBOR Q2BOR LIEBOR
Results are unfortunately the same.

Attached are the sisyphe and telemac steering file. I use the V6P1 version. There is also the fortran file.
I would be very glad if you could help me.
