I am trying to run the model in fluent solver. and I tried to get the better result with convergence. I tried both steady and transient phase. My first problem is, its not converging and when i try transient phase its shows an error " fl point exception" and I setup the "escaped mass" to track the particle in steady state but when I run the model, In each iteration I am getting the zero value.

also can you recommend me the best parameter in fluent that best fit for this model.
I have a nozzle in which one side of the nozzle is attached with incoming flow and the other side of the nozzle is attached to the hot rotating tube. The incoming flow in the nozzle is nitrogen and powder.
