air blast atomizer problem
 

hi
i am doing a DPM problem with air-balst-atomizer as injection type. the tracking is unsteady and coupled. I enter the start time as 0 and stop time as 400 s but after some iteration there isnt any injected particles and the number o ftracked is constant. when i change the stop time as another value less or more some particles are injected but again the number tracked will be constant. why this happens?

In the SET INJECTION PROPERTIES dilog box select .. number of particle streams as 60 and stop time as 100... then run and see.

What time step are you using ?
