DEM and CFD coupling software for students
 

I want to do thermal analysis of a grain dryer. To create and flow Grain particles in Bulk I want to use DEM (Discrete Element Modelling) and for thermal part, CFD (Computational Fluid Dynamics) for that. Can somebody please suggest a software in which both of these could be used or any two softwares which need to be coupled to get the required simulation and results?
