Modeling cold storage

  I made a question some time ago (https://forum.ansys.com/discussion/comment/154692#Comment_154692).
  Since then, I'm still trying to figure my problem out. I want to simulate the dispersion of decomposing tracer gas in a cold storage chamber. The problem arises in modeling this air recycling, which must have conservation of the tracer gas. I don't need to model and simulate the recycling region. I just want all the tracer gas that goes out through the outlet to come back to the diffusers. Below are some images from the geometry, the yellow box is the recycling region that I want to eliminate. I found on an old forum thread (Coupling outlet to inlet) with a UDF that did this coupling, but for the air humidity. If anyone could help me translate it to a generic tracer gas, I would appreciate it, being reading the UDF manual for some time, and didn't get far.

  Hello,
  Ansys employees will not be able to do this. If anyone else in the forum would like to pitch in, they can.
  I would suggest you get started with writing a UDF and let us know if you run into any issues, we'll assist you.

  Equally, if you use an expression it may be easier.
