Hello,
What do you exactly want to do? Run a TELEMAC-3D computation with tracers salinity + temperature but what is your SERAFIN file with interpolated salinity and temperature for? Is it interpolated at every time step, every a number of time step, or just at initial condition?
If just at initial condition, you should have alread read my answer in one of your previous post:

If this is not enough, please clarify what you exactly want to do.
