open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,
In telemac_3d manual I do not find the Keyword "LAW OF TRACERS DEGRADATION" . It is not in 3d?
In this fall , how can I simulate a dregradations law? is there some .f_file?

Hello,

You need to take subroutine source_trac.f (library Telemac-3D) in your Fortran file and modify it. There is an example of radio-active decay which is probably what you want, with just 2 lines to uncomment. Basically you have explicit (S0TA) and implicit (S1TA) source terms. S0TA and S1TA are blocks that contain as many arrays as tracers (refer to the guide for programming in the Telemac system for more details on blocks, BIEF_OBJ structures, and subroutine OS).

With best regards,
