open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

I need describe the cas. file considering 12 tracer sources, but I don't know how to write. In fact are 6 coordinates of source and 2 parameters (DN and DP).

I tryed write the information in sequency (like example). But the Telemac gave me a ERROR (KeyError: 'VALUES OF TRACERS')

Thanks

Hello,

Instead of:
VARIABLES FOR GRAPHIC PRINTOUTS = 'U,V,S,B,H,Q,M,L,T(1,1),T(1,2),T(1,3),T(1,4),T(1,5),T(1,6),T(2,1),T(2,2),T(2,3),T(2,4),T(2,5),T(2,6)'
try:
VARIABLES FOR GRAPHIC PRINTOUTS = 'U,V,S,B,H,Q,M,L,T*,T1*'

For the names of tracers try:
NAMES OF TRACERS =
'DN,1 [mg/L] ';
'DN,2 [mg/L] ';
etc. (16 characters for name and 16 for unit)

INITIAL VALUES OF TRACERS : 0. (is OK, will be given for all values, if problem, give 12 numbers...)

VALUES OF THE TRACERS AT THE SOURCES : I'am afraid you have to give 12 * 6 values but you can do it with several lines. First the 6 values at the sources of the first tracer, then the 6 values for the second tracer, and so on... To avoid any problem, cut a line after ; only, not in the middle of a number.

With best regards,

Jean-Michel Hervouet

Thank you very much for your reply.
Regarding the last keyword: VALUES OF THE TRACERS AT THE SOURCES
I thought I could give only 12 values, because it means that the 1st value is DN at the 1st source, 2th value is DN at the 2th source, ... , 6th value is DN at the 6th source, 7th value is TP at the 1st source, ... 12th value is TP at the 6th source.
But you mention 12 * 6 values, what do you mean exactly with that? A matrix? But I don´t get the reason...
Thank you again.
Regards

Hi

I think there was a misunderstanding between you and Jean-Michel.

If you want only 2 tracers rejected at 6 sources, you have to give 12 values.

As you indicate in your file Number of tracers = 12, if you have 6 sources, you have to give 12*6 values...

The main difference is that in the first case, you will have only 2 tracers in the result and you could not identify from which source it comes.

Hope this clarify the problem

regards

Hi,

I have a question about it, since I do not understand entirely this 12*6 values to be given and it seems very complicated

If one then run 2 different computations 1) and 2) separately:

1) for one nutrient for example phosphorus from the 6 sources
2) for the other nutrient for example nitrogen from the 6 sources

Then the keywords to be given are (e.g. for 1) dissolved phosphorus):

VARIABLES FOR GRAPHIC PRINTOUTS = 'U,V,S,B,H,Q,M,L,T1*'
NUMBER OF TRACERS : 6
NAMES OF TRACERS :
'DP,1 [mg/L] ';
'DP,2 [mg/L] ';
'DP,3 [mg/L] ';
'DP,4 [mg/L] ';
'DP,5 [mg/L] ';
'DP,6 [mg/L] ';
INITIAL VALUES OF TRACERS : 0.;0.;0.;0.;0.;0.

ORDINATES OF SOURCES = 9030837.0000000; 9030768.0000000; 9029034.; 9028453.; 9027845.; 9025881.
WATER DISCHARGE OF SOURCES = 1.0
VALUES OF THE TRACERS AT THE SOURCES = 0.0410;0.1547;0.0152;0.1289;0.1172;0.1172
COEFFICIENT FOR DIFFUSION OF TRACERS : 1.E-4

Correct?

Thank you.

Best regards

Hi
Don't mix things
You want 1 tracer only but released at 6 sources!
(Except if you want to follow the same tracer from the 6 sources)

You should have 6 water discharge of sources

Otherwise it should works

regards

Dear all (Hervouet, coulet and Elena),

thank you for all patience and help.

After some attempts, finally It's working.
Now I will try for the second source and different conditions, including with initial value of tracer.

I hope that now will be everything ok

Have a nice day.
Best regards
