What are the methods of continuous phase simulation in MFIX?DNS 、LES 、RANS?

Hello everyone, what are the methods of continuous phase simulation in MFIX?Do these methods include DNS, LES, RANS?if so, in which module of MFIX are these three methods?If not, can these three methods be implemented in code?

MFiX has the k-epsilon turbulence model (RANS). MFiX is open source, you can implement other RANS turbulence models or LES if you spend sufficient time studying the code.
