How to modify particle introduction (Lagrangian)

Kushagra

Hi,

I want to write a function (code) in CFX so that the solver introduces some 100 partiles at certain time step (only once) and track them.

What part of CFX documents should I read for creating such functions? (I am confused what are they called...User defined function OR CEL OR what .....)

I will highly appreciate if some one can help me in writing this code.

Thanks so much, Kushagra
