The detailed implementation for solving a passive scalar transport equation without diffusion term, i.e.

with be the scalar concentration.
(1) If scalar velocity equals to the "carrier fluid'' (the fluid solved in the Navier-Stokes equation), i.e., , how
to implement the scalar source term in source files?
(2)If , how to consider this velocity difference between passive scalar and "carrier fluid''?
Thanks!

Hello,

I'm not sure about this (and not too familiar with that model), but try to look for "drift" in the documentation and examples, as this may be adapted to your needs. I'll also suggest a colleague who worked on drift to check your post.
