droplet impact on walls
 

I am using fluent to simulate the process of droplet impacting on hot wall.i use DPM model.the question is how can i use UDFs to trace the additional droplets resulting from the impingment on hot wall.i can determine the velocity and direction of splash droplets but i dont know how to add these splash droplets to the computation process, is fluent capble of change the droplet nomber in computation process?

thank all in advance
