Initialization
 

I used laminar Flow through a conical nozzle....converged the solution
i added inert-particles didnt intialized the solution again , i had same results...
I initialized it again then different results...
I want to ask if i shift to turbulent flow , i have to initialize again or just run same solution with viscous modle added...

one more thing wat it menas REVERSE FLOW at INLET .....

how to avoid it?
