Trubal saturated version

Dear all,
Hi
I am a PhD student at university of Tehran, I am searching about an opensource DEM-CFD program for studying micro mechanical characteristics of contacts,
my major is geotechnical engineering, I have a modified Trubal program that have micro mechanical subroutines and my first choice is to find a Trubal saturated version, an opensource Trubal code that is coupled with a CFD program,
I will be grateful if any one could help me by this matter,
Bests
