[MITgcm-support] How to change advection-difussion equation for only salinity tracer

[JOSE ALFREDO OCEGUEDA SANCHEZ]

Hi, I'm trying to simulate a turbidity current for my undergraduate thesis,
and for that, I'm using salinity, and \beta_{s} to make a high-density
fluid. I'm using the Third-order direct space-time with flux limiting
advection scheme for salt and temperature (tempAdvScheme=33, saltAdvScheme
= 33) but in order to correctly simulate the turbidity current, I need to
add a constant settling velocity of sediment in the ẑ direction. I think
that the file I need to change is gad_dst3fl_adv_r.F and add the constant
settling velocity there, but my question is how to do that only for
sediment concentration (salt in my case) and not in both tracers
(temperature and salt).

Thanks in advance for your help.
