open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,everyone

I give a point source with tracer in my program. I set WATER DISCHARGE OF SOURCES =100.D0 and VALUES OF THE TRACERS AT THE SOURCES =1.D0. The first is the discharge at the source(m3/s) and the second is the source value of the tracer(kg/m3). That is right? but the max concentration of tracer is not 1.
I want to set the concentration of the tracer at the source to unit 1. How can I do that?

Thank you very much.
Best regards.

Hello,

This is impossible and against what really happens. The quantity of tracer brought by a source is immediately diluted in the volume around the point by water coming from elsewhere. If you want the source point value to be at 1, for some reason, you could rescale your results by multiplying them by a constant. However the real dilution factor will be biased by this.

Yeah, you are right. I see. Thanks a lot.
