LES vs DPM
 

hi, i'm working on a combustor chamber feeded with liquid kerosene using discrete phase model. now i'm tryng to performe some LES simulation but indipendently of the convergence of the starting field i obtain very large oscillation of residual (2 or 3 order of magnitude). now i find in the compatibility chart of fluent guide that les and dpm are not compatible. could any one help me to solve this problem?
