Imodeli ye- CFD-DEM, noma imodeli ye-Computational Fluid Dynamics / Discrete Element Method, inqubo esetshenziselwa ukumodela noma ukulingisa amasistimu ahlanganisa uketshezi nezinto eziqinile noma izinhlayiya. Ku-CFD-DEM, ukunyakaza kokuqinile okuqinile noma isigaba sezinhlayiya kutholwa I-Discrete Element Method (DEM) esebenzisa imithetho yokunyakaza ka-Newton kuyo yonke izinhlayiya, kuyilapho ukugeleza koketshezi oluqhubekayo kuchazwa izibalo ezimaphakathi zendawo ze-Navier-Stokes ingaxazululwa kusetshenziswa indlela yendabuko yeComputational Fluid Dynamics (CFD).Ukusebenzisana phakathi kwesigaba soketshezi kanye nesigaba sokuqinile kumodelwa ngokusetshenziswa komthetho wesithathu ka-Newton . Ukufakwa okuqondile kwe-CFD ku-DEM ukuze kufundwe inqubo ye-gas fluidization kuze kube manje kuzanywe ngu-Tsuji et al. futhi kamuva nje nguHoomans et al., Deb et al. kanye noPeng et al. Uhlolojikelele lwakamuva ngezinkambu zezicelo lunikezwe u-Kieckhefen et al. I-OpenMP iboniswe iphumelela kakhulu ekwenzeni izibalo ezihlanganisiwe ze-CFD-DEM kuhlaka olufanayo uma kuqhathaniswa ne- MPI ka-Amritkar et al. Muva nje, kusungulwe isu elihambisanayo lezilinganiso eziningi . Ngokuvamile, isizinda sokulingisa sihlukaniswe izizinda eziningi ezingaphansi futhi inqubo ngayinye ibala isizinda esisodwa esingaphansi sisebenzisa ulwazi lomngcele oludlula i-MPI; kusizinda ngasinye esingaphansi, ama-CPU asetshenziselwa ukuxazulula isigaba samanzi kuyilapho inhloso evamile ye-GPU isetshenziselwa ukuxazulula ukunyakaza kwezinhlayiya.
